It affects the build, and if used as a static file, can reliably be
tracked using the `-MF` mechanism.
gcc/cp/:
* mapper-client.cc, mapper-client.h (open_module_client): Accept
dependency tracking and track module mapper files as
dependencies.
* module.cc (make_mapper, get_mapper): Pass the dependency
tracking class down.
gcc/testsuite/:
* g++.dg/modules/depreport-2.modmap: New test.
* g++.dg/modules/depreport-2_a.C: New test.
* g++.dg/modules/depreport-2_b.C: New test.
* g++.dg/modules/test-depfile.py: Support `:|` syntax output
when generating modules.
