There's already concern that these names are too long as it is. This
name is more specific which is nice.

However, a better long-term solution would require changes on the MSVC
side. The `-internalPartition` flag being the way it is makes users have
to consider the `export` bit. If instead, `CXX_MODULES` can instead be
*any* TU that creates a BMI, the non-standard `module M:part;` impl unit
can then be something that only those that use it have to deal with
(maybe being `-implementationPartition`?). Is there any hope of moving
the flag to being present on the non-standard thing instead of the
standard-compliant unit?

Thanks,
