Alyssa Rosenzweig 23d07d7d0c OpcodeDispatcher: fix folding negative offsets for 32-bit 
I don't know what I was thinking when I wrote that code. Drop the silly logic
and let ConstProp inline the immediates. This fixes a lot of silly code
generated for 32-bit.

Ryan Houdek 2f8c5b4820 FEXCore: Pass HostFeatures in to CreateNewContext directly 
The class constructor for ContextImpl::CPUID requires HostFeatures to be
available at construction time. Pass the host features struct directly
through during construction time instead, which cleans up the interface
slightly and fixes that issue.

Ryan Houdek a1f55f0b0b HostFeatures: Removes feature flags always supported by FEX 
These are only missing if using the hostrunner and the CI machine
doesn't support that particular feature. FEX otherwise always supports
these feature flags so they don't need to exist as options.

Just check the feature bit directly in the HostRunner frontend for these
bits.

Ryan Houdek e84848b16b FEX: Moves HostFeatures querying to the frontend 
This moves the CPU feature querying to the frontend. The primary purpose
here is for the wow64 frontend to not require linux-isms for querying
these features. This is required since non-Linux environments don't have
the "CPUID" feature for reading EL1 MSRs in EL0.

Wiring up the remaining wow64 registry querying is left for a future
exercise.

This also technically removes an xbyak requirement from FEXCore for when
building the x86 Test harness runner, but that doesn't really matter for
regular use cases.

Ryan Houdek e613876e9d AVX128: Optimize all cases of vpermq 
Started by cherry-picking some cases from the variants that appeared when running
Steam, games, AV1 convolve tests, openssl, ffmpeg, libjpeg-turbo,
openh264, libvpx, gemmlowp, libyuv, and dav1d.

Then turned it around and optimized them all since all variants end up
needing to be split in to two halves, that effectively means we need to
have 16 implementations, plus a couple of special cases for duplicated
results.

Fixes #3795

Billy Laws ccf332d48e Arm64Emitter: Reload STATE before SRA fill on ARM64EC 
While ARM64EC code cannot use x28, it can be cleared by the kernel
when performing syscalls etc so restore it from the TEB to be safe.

Ryan Houdek 6ff3c90af3 CodeEmitter: Removes vestigial vixl usage 
- IsImmLogical already existed in our CodeEmitter. We just forgot to
  allow nullptr arguments and to use it.
- Adds an equivalent IsImmAddSub helper and uses it

This gets us closer to removing vixl's global initializers from FEXCore.
