This is going to be necessary for the offline compiler work.
Also allow FEXGetConfig to print the same registers in the correct
format for easy fetching.
The MIDR querying is inherently OS specific and needs a bit of special
casing. Instead let the frontend inform FEXCore how many CPU cores there
are and their MIDRs instead.
This lets us keep the Linux specific code in the frontend.
If we query the CPU flags ourselves then vixl is no longer a
compile-time or runtime dependency unless the vixl disassembler or
simulator is built.
A bit spicy from all the feature bits we need to load up.
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.
