LC 70eafc4f6f FEXGetConfig: Mark helpers as static where applicable
Makes them internally linked, and also lets them be caught by the
compiler when they're unused.

LC 38cbd2aeb2 FEXGetConfig: Add convenience option for dumping system/tso info
Just lets you get a broad overview all at once instead of needing to
type out every long command.

Now it's easier to be lazy and just pass "-e", or "--all-emu-info".

```
warning: redirecting incorrect #include <sys/poll.h> to <poll.h> [-W#warnings]
warning: redirecting incorrect #include <sys/signal.h> to <signal.h> [-W#warnings]
```

include headers instead of sys/headers.

Ryan Houdek 856fb1e636 Snapdragon X2 Elite fixes
- RNDRRS is still broken on this CPU
- Fault granularity checking needs to use loads
  - stlxp does monitor check before alignment check, use loads for all
    for consistency
  - Fault granularity is still 16B which matches LSE2 requirements.
- X2E still only ships a 19.2Mhz cycle counter, so still only
  ARMv9.0-a hardware
- Adds product name to CPUID
  - Oryon-3 being CPU PartID 2 isn't a mistake.
  - No distinction between Oryon-1 and Oryon-2, both are partid 1.

crueter 872aec20b8 [cmake] more parenthesis cleanups, linker gc module, more same-line stuff
I may have gotten carried away.

- I missed some stuff for end parenthesis because I accidentally
  searched within project files instead of the entire directory (so some
  thunk/test/windows stuff was missed), cleaned those up.
- `INTERFACE`, `PUBLIC`, `PRIVATE`, `RUNTIME`, `LIBRARY` should be on
  the same line as the target name. (I should really invest in making a
  style guide...)
- Some short statements were unnecessarily split across multiple
  lines--cleaned those up
- Made a common `LinkerGC` module that applies gc-sections etc. to a
  target in Release mode
- Usually for functions you want to have something on the first line,
  e.g. `FILES`/`DIRECTORY` for install, or the target/a positional
  argument, etc etc. Not always though, notably for some custom_command
  calls

TODO:
- What's with the `list(APPEND LIBS...)` stuff? It's used really
  inconsistently, sometimes not at all, sometimes it looks like there're
  duplicates? A more thorough cleanup is in order there.

crueter 9e8463d6d7 [cmake] refactor: compiler and architecture handling
- Do compiler/architecture checks EARLY, don't waste time doing random
  configuration stuff if the user can't even compile in the first place
- MSVC is unsupported, I assume? So add a check to disallow. There's
  literally no MSVC or MSC_VER checks anywhere, so...
- Rather than using the MSVC architecture definitions, use our own
  `ARCHITECTURE_arm64` et al. Hijacking existing "standard" definitions
  is a very bad idea. Also makes it more readable in CMake
- Change the x86 host check to `x86|amd64`. Some systems still refer to
  themselves as x86 despite being 64-bit for... reasons, and I saw one a
  very long time ago that referred to it as amd64. This should
  basically never come up, nor is it really relevant given that FEX is
  for arm64... but it kinda annoyed me so whatever.

TODOs:
- Should we check `CMAKE_SIZEOF_VOID_P (equal) 64`? I don't think anyone
  is even trying to compile this thing on armv7 or older, but might as
  well? maybe?
- What's the status of *BSD, Solaris, macOS? Technically macOS does
  support Wine, not sure about the others.

crueter 588fec3b89 [cmake] reduce usage of trivial variables
Trivial variables like SRCS, NAME, etc. actually do more harm than good.
They *will* make your IDE mad, and are also less readable. Remember:
verbosity is not a bad thing! Usually

Also: did a few tiny cleanups that I missed from my `endpara` PR.

crueter 43173df446 [cmake] prefer end parenthesis on same line, no space after some calls
- Some CMake LSPs have aneurysms when you put the end parenthesis on a
  different line. Annoying? Yes, but this is all we can really do about
  it for now.
- `set`, `option`, and `message` should not have spaces before their
  opening parenthesis.

crueter ec1d9aeafa [cmake] propagate -ISource to all Tools
Rather than individually adding `${CMAKE_SOURCE_DIR}/Source` as
an include directory to each target, just use `include_directories` once
in the Tools directory and each subsequent target will have this
propagated down.

Also removed a seemingly unnecessary `-I` in LinuxEmulation--maybe
needed? But I can't test compilation right now as I don't have an ARM
development environment on hand for the next day or two.

Ryan Houdek 7ceadc6b5b Move config layers to the frontend
FEXCore has no need to understand how to load these layers. Which
requires json parsing.

Move these to the frontend which is already doing the configuration
layer setup and initialization tasks anyway.

Means FEXCore itself no longer needs to link to tiny-json which can be
left to the frontend.

This will be useful for keying specific executables to steamids.
This is sadly required because a bunch of games end up naming themselves

generic name.

Ryan Houdek 0dc33ec893 cmake: Remove the static-pie compilation option
Due to glibc issues around static applications doing dlopen this is a
fundamentally broken option and no longer supported by FEX.

Remove the option entirely as to not be confusing.

We kept this around initially for chroot support, but with our RootFS
mounting AArch64 folders inside the chroot this isn't necessary anymore.

Ryan Houdek 5fe6afc270 FEXServer: Adds new FEXServer service
This is a relatively invasive change since multiple things needed to
happen at once.

* Socket based logging is removed
  * Logging has been replaced to only support stdout, stderr, and server
  * Server is now default and replaces what FEXLogServer did
  * Server logging now uses a pipe instead of a socket
  * Can be faster than stderr and stdout since the application doesn't
    need to wait on terminal output

* FEXMountDaemon has been removed
  * Functionality has been merged in to FEXServer

* FEXServer is always executed on FEX initialization time
  * Similar in behaviour to Wine's wineserver
  * Can explicitly start this before using FEX for logging purposes
  * Stays around until all instances of FEX exit
  * Will stick around for a short amount of time in case of spurious
    execution

* FEXServer will soon be extended to do more than logging and squashfs
  mounting

* FEX rootfs scripts will need to be updated to support this path
  * Just means rbinding the /tmp folder and forcing a FEXServer instance
    to be alive
* Pressure-vessel works fine in this case since FEXServer will already
  be running
  * It already rbinds the host /tmp folder which is why this works

Ryan Houdek 4ccd68af8a FEXMountDaemon: Fixes shutdown race conditions
This solves a problem where sometimes FEX would spin up a new process
while FEXMountDaemon was in the process of shutting down. Breaking
things on both sides.

Now the race conditions are squashed that I could see.

Also fixes one race where FEX is starting up and FEXMountDaemon is
spinning up. This case is where FEX managed to pull the lock file just
before it got deleted. Then sent the FEXMountDaemon a request to be
observed. With DGRAM sockets we would fire and forget. Use a STREAM with
a ack result so we know we can return.

Puts the visibility of the main layer, application layers, and
