Subject: [PATCH] [flang] Add driver support for x86 -m* target feature flags
Added FlangOption visibility to m_x86_Features_Group so flags such as -mavx,
-mavx2, and -mavx512f are accepted by flang and forwarded as -target-feature
to -fc1 via the shared Clang driver logic.
Also extended target-cpu-features.f90 with grouped driver tests that cover
m_x86_Features_Group options, including representative -mno-*, APX cases
