openmpi: add two_level_namespace variant for MacOS (#47202)

Browse Source 
* Add two_level_namespace variant (default is disabled) for MacOS to enable building
executables and libraries with two level namespace enabled.
* Addressed reviewer comments.
* Moved two_level_namespace variant ahead of the patch that uses that variant to
get concretize to work properly.
* Removed extra print statements

# Patch to allow two-level namespace on a MacOS platform when building

# hardwired in. In spack, this only works for openmpi up to versions 4,
# because for versions 5+ autoreconf is triggered (see below) and this
# patch needs to be applied (again) AFTER autoreconf ran.
