SyscallsSMCTracking: Workaround assert in ELF mapping

Ryan Houdek 5902b175f9 SyscallsSMCTracking: Workaround assert in ELF mapping 
The ELF tracking thing has an expectation that only portions of ELF
files that are described in the program headers will be mapped
executable. This doesn't hold true as programs will remap random
portions of ELF files as executable. In the case that this occurs, don't
assert out and instead print a warning.

This was discovered as Node.js remaps a portion of itself executable
that isn't described as such in the program headers. I also have a local
unittest that exposes the same problem. I had discovered same problem in
some other program with #5038.

Also fixes a bug where sometimes completely anonymously mapped
executable sneak in and cause a crash, which is kind of silly.

Ryan Houdek f3f134f9de FEXServer: Add support for FEX Logging control 
Always enables FEXServer log thread when built for Steam so that clients
can be controlled with `STEAM_FEX_LOG=1`. FEX logs will then always go
to FEXServer and those can get directed to wherever pressure-vessel
chooses.

Ryan Houdek cdbf5d57bd Steam: Adds FEXServerManager 
This is fairly simple. Needs to be installed alongside FEXServer, so
that it can start it in a portable config.

- Starts a FEXServer
- Tells pressure-vessel when FEXServer is ready
- Keeps FEXServer alive with the `watch_fd` as long as the process lives
- Listens for pressure-vessel to be shutting down
- Exits once pressure-vessel exits, also letting FEXServer shutdown if
  no FEX instances are alive.
