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)
