Ryan Houdek 7ca757bb6d FEXCore: Move CPUInfo to FEX 
This is only ever used in the frontend now.

Ryan Houdek 5767c61a91 FEXCore/Emitter: Stop creating a vector on the heap 
In the Push/Pop CalleeSavedRegisters these vectors were getting created
on the heap, allocating memory and then just iterating them.

Just use a std::array which makes it stop allocating memory and saves
the number of instructions.

On the slow path these were pushing and popping in the wrong direction.
Switch them around to ensure the unittests work.

Billy Laws 02d3a319f9 OpTables: Disable thunk opcodes on win32 
They are of no use here, and are quite frequent in never-taken blocks in Denuvo games

Ryan Houdek f9b369c550 Telemetry: Removes unnecessary indirection 
Telemetry value address generation was forcing an indirection at all
times which was unnecessary. These values live in the BSS, zero
initialized at process start and is unnecessary.

Instead change the wrapper defines to directly operate on the enum
passed in which saves an indirection on all of these telemetry
operations (except for the ones in the JIT which are required to be PIC
compliant).

This also fixes an annoying warning about
`FEXCORE_TELEMETRY_STATIC_INIT` causing initialization and destruction
order being unspecified, so two wins.

Ryan Houdek 0599d80b13 FEXCore/Frontend: Changes how VEX operand encoding flags are encoded 
These three options are mutually exclusive with each other and could
potentially result in invalid encodings of the table on accident.

Change over to a 2-bit bitfield to encode if the operand that consumes
the VEX option is none, destination, 1st src, or 2nd src.

This ensures the table can't ever be incorrectly encoded.
