Enable AVXVNNI microkernels for mobile platforms
There is another PR that eliminates XNN_PLATFORM_MOBILE, which would also satisfy this Android requirement? https://github.com/google/XNNPACK/pull/8509
This PR would fully enable all x86 microkernels on all devices. If the NDK doesnt support a new ISA, the bazel build has a mechanism to disable by ISA. e.g. --define=xnn_enable_avx512amx=false
For CMake we rely on compiler version, which mostly works. To find compiler versions, I found godbolt is awesome for this, letting you take a code snippet and try gcc, visual c and clang, with different versions, to find which version is required for the compiler flag to be recognized. pytorch cmake has a different approach of compiling a code snippet with the flags needed, and if that doesnt work, the ISA is disabled.
