Ryan Houdek cb9eb00339 Frontend: Remove DST_RDX flag 
Easiest initial one to remove. Adds a helper that matches behaviour of
previous StoreResult around zero-extend mechanics to make things easier.

Pierre-Loup A. Griffais aa9ae27932 Frontend: mark more (all?) imm32s for DiskCache patching 
Including big C7 who was very prevalent.

Pierre-Loup A. Griffais f9623af073 Frontend: mark a bunch of disp32s for DiskCache patching 
Only when at the end for now, could improve with multi-field tracking.

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

Pierre-Loup A. Griffais c92805475d DiskCache: detect inline data, hash around it and patch it on Lookup 
Only detect certain kinds of mov reg,immediate so far, which was the bulk of
Mono JIT activity.

Ryan Houdek 4048faa54b FEXCore/Frontend: Ensure instruction sizes account for sha256 in thunk op 
Fixes the hashing mechanism from DiskCache.cpp, allowing it to properly
handle thunk relocations.

LC ab4fb7b3ad [SVE256] Ensure insertion behavior for AES operations on SSE 
These slipped through, so now we can add tests for them to prevent that
from happening again.

LC df41b85827 OpcodeDispatcher: Merge VPINSRB/VPINSRW handling 
We can just pass the size through Bind instead of having two functions
that effectively do the same thing, only differing on element size.

LC c62805e86d OpcodeDispatcher: Make use of Bind consistently 
We had a few places that were using Bind, and a few other places
that were using specializations as a means to composing the instruction
tables. Instead, we can just use Bind consistently, which lets us tidy
up a bunch of the implementations (and gets rid of some unnecessary
codegen).

Tony Wasserka 22faa58e0b X86Tables: Use explicit type for SecondInstGroupOps definition
