  [AArch64] Implement __builtin_cpu_supports, compiler-rt tests. (#82378)

The patch complements https://github.com/llvm/llvm-project/pull/68919
and adds AArch64 support for builtin
`__builtin_cpu_supports("feature1+...+featureN")`
which return true if all specified CPU features in argument are
detected. Also compiler-rt aarch64 native run tests for features
detection mechanism were added and 'cpu_model' check was fixed after its
refactor merged https://github.com/llvm/llvm-project/pull/75635 Original
RFC was https://reviews.llvm.org/D153153
