[common/cpu_detect] Remove SSE/SSE2/FMA4/AVX_VNNI detection (#3979)
Some checks are pending
tx-src / sources (push) Waiting to run
Check Strings / check-strings (push) Waiting to run
Removes Eden's own feature detection for SSE, SSE2, FMA4 and AVX_VNNI, in order to clean up code and make the function slightly lighter. They are all unused and I have specific reasons for their removal:
- SSE/SSE2 are always true for x64
- FMA4 is a deprecated AMD exclusive extension, replaced by the regular FMA and was logged here as "FMA" for no reason
- AVX_VNNI simply does not seem applicable for Eden (but can still be checked for through Xbyak's feature detection if necessary)

b37f669584 common/x64: Use TSC clock rate from CPUID when available
The current method used to estimate the TSC is fairly accurate - within a few kHz - but the exact value can be extracted from CPUID if available.

c802f8fbd2 cpu_detect: Add additional x86 flags and telemetry
Adds detection of additional CPU flags to cpu_detect and additions to telemetry output.

This is not exhaustive but guided by features that [dynarmic utilizes](bcfe377aaa/src/dynarmic/backend/x64/host_feature.h (L12-L33)) as well as features that are currently utilized but not reported to telemetry(invariant_tsc). This is intended to guide future optimizations.

AVX512 in particular is broken up into its individual subsets and some other processor features such as [sha](https://en.wikipedia.org/wiki/Intel_SHA_extensions) and [gfni](https://en.wikipedia.org/wiki/AVX-512#GFNI) are added to have some forward-facing data-points.

What used to be a single `CPU_Extension_x64_AVX512` telemetry field
is also broken up into individual `CPU_Extension_x64_AVX512{F,VL,CD,...}` fields.

31f8d6f0cf cpu_detect: Compact capability fields
As this structure gets more explicit, bools can be bitfields and
small enums can use smaller types for their span of values.
