Introduce `KMP_COMPILER_ICX` macro to represent compilation with oneAPI compiler. This is just paired with `KMP_COMPILER_ICC` in most places

Fixup flag detection and compiler ID detection in CMake. Older CMake's detect IntelLLVM as Clang. Check for the `__INTEL_CLANG_COMPILER` pre-defined macro to determine if actually using oneAPI compiler.

Fix many compiler warnings from oneAPI compiler (both Linux and Windows). Many are unused variable warnings.

Fixup many of the tests to have non-empty parallel regions as they are elided by oneAPI compiler. Also have OMPT tests include `-fno-omit-frame-pointer` when available as oneAPI removes it by default.
