Ryan Houdek 229151f878 FEXCore: Have the Syscall IR op jump to the dispatcher 
Have it treated as a block terminator IR and instead of doing
syscall+exitfunction, just do syscall and jump in to the dispatcher.

This is necessary for code invalidation and reuse for code that is stuck
in long running syscalls. We'll need to do something similar for thunks
later, although the recursive nature of thunk+callback can make that a
little squirrely.

Ryan Houdek 5006e02498 Dispatcher: Fixes range check of InterruptFaultPage 
This one wasn't updated and it's right at the limit of what it can
handle.

Ryan Houdek a0ba36eb1b SharedCodeBuffer: Skip VMA naming when JITSymbols are enabled 
For some reason `perf top` prefers VMA names over perf symbols. So
disable them when any JIT symbol option is enabled. Breaks WTF tracking
for those buffers but because it's debug, we kind of have to.

Pierre-Loup A. Griffais 7a82b07bfd DiskCache: optional memory buffer for faster lookups 
May reserve a tiny area for small blocks in general, but will also be useful
for LuaJIT in anon-diskless mode.

Pierre-Loup A. Griffais 3f8f886f65 Frontend: patch cmp imm8 for cache 
Usually imm8 seem more likely to be a function of the code around them, but
this one seems used by Mono for varying data over execution of same code.
Maybe an ID of some kind.

Pierre-Loup A. Griffais 56a4f11ddb Frontend: avoid cache patching for certain cases with data unlikely to change 
The MOV heuristic shaves off a ton of patch sites (storage and overhead on
Lookup) where the data doesn't seem to change in practice.

Pierre-Loup A. Griffais 1695d742b1 DiskCache: on Store, make unaccounted-for DataMasks non-fatal 
By going through relocations before computing/hashing extents, we can simply
undo datamasks that haven't been claimed by the backend instead of failing
the whole Store. They fall back to being part of the normal hashed extents.

WOW64: Use CHPEv2 for suspend and exception support

Ryan Houdek 91bbce5a96 FEXCore/OpcodeDispatcher: Fixes syscall instruction on Linux 
I forgot on Linux by default we didn't have the syscall instructions
count as block end. Change this so that it counts as block end now.

This has the additional benefit that now the frontend needs to modify
the RIP manually as well which is fine as it's what arm64ec and wow64
does.

Also add back the UnimplementedOp in RDPID that accidentally got caught
up. Also increment DiskCache version as both changes will change
codegen.

Fixes #5942

Jacek Caban af04940466 WOW64: Use CHPEv2 for suspend and exception support 
CHPE_V2_CPU_AREA_INFO is the mechanism used on ARM64EC to coordinate
thread state, suspension and exception handling with the kernel.
It's typically set up by ntdll for ARM64EC processes, but Wine uses
the TEB pointer without restricting where it's coming from. Set
ChpeV2CpuAreaInfo in FEX WOW64 thread initialization.

Fixes 32-bit debug events and a number of CPU context handling tests.
Reduces the number of wineserver round-trips required for suspend and
avoids the need for remote thread creation for inter-process suspends.
