[Driver][X86] Add flang visibility for -mapx-features= (#97525)
The default visibility of `m_x86_Features_Group` is `ClangOption,
CLOption`. For x86, we expose `-march` to flang but not `-m<cpuid>`.
`apxf` is special b/c it contains several independent features like
`egpr, ndd, ppx, push2pop2, ccmp, nf, cf` and `zu`.
Users may would like to turn on part of features in different cases
1. enable `ndd` only when writing a code-size sensitive library
2. disable `ccmp`, `cf` when building component has strong security
request on caches
Hence, we expose `-mapx-features=` to flang for Fortran users.
