Iain Sandoe 69350e569d [C++20][Modules][3/8] Initial handling for module partitions.
This implements the parsing and recognition of module partition CMIs
and removes the FIXMEs in the parser.

Module partitions are recognised in the base computation of visibility,
however additional amendments to visibility follow in subsequent patches.
