CMake: Teach qt_internal_add_simd to exclude given osx architectures

qt_internal_add_simd can now take an EXCLUDE_OSX_ARCHITECTURES list of
values which specifies for which architectures the simd compile flags
should not be added.
This is relevant for macOS universal builds.

Example

CMAKE_OSX_ARCHITECTURES is "x86_64;arm64"
EXCLUDE_OSX_ARCHITECTURES is "arm64"
SIMD is avx2
the final compiler flags that will be added are "-Xarch_x86_64 -mavx2"

Slightly, clean up the function implementation and document its
arguments.

NAME handling has been removed because it's dead code that hasn't been
removed as part of 1b7008a3d784f3f266368f824cb43d473a301ba1.
