c++/modules: Fix include translation for already-seen headers [PR99243]
After importing a header unit we learn about and setup any header
modules that we transitively depend on. However, this causes
'set_filename' to fail an assertion if we then come across this header
as an #include and attempt to translate it into a module. We still need
to do this translation so that libcpp learns that this is a header unit,
but we shouldn't error just because we've already seen it as an import.
Instead this patch merely checks and errors to handle the case of a
broken mapper implementation which supplies a different CMI path from
the one we already got.
As a drive-by fix, also make failing to find the CMI for a module be a
fatal error: any further errors in the TU are unlikely to be helpful.
So closing.
