MSVC needs the transitive closure of module usage to compile.

Not all filesystems support `:` in the name, so replace it with `-`. As
`-` is not otherwise allowed in module names anyways, there is no risk
of conflict.

The fundamental issue is that the set of files is dependent upon the
target being used, not the consuming target. Since these generator
expressions apply to the in-effect configuration, `MAP_IMPORTED_CONFIG`
mechanisms may change the set of modules that are available. To avoid
this, deny exporting any target with configuration-dependent `FILE_SET`
information for C++ modules.

This directory will be used to store build-discovered information about
targets such as the modules provided by the files in the relevant
`FILE_SET` types.

A directory is used because basing the name on a `<FILE_NAME>-*.cmake`
pattern makes it end up being globbed in the configuration-dependent
information mechanism. Since old modules and targets may be around,
unconditionally including them may refer to targets that do not actually
exist.

The collator will use this to generate property settings for the
imported targets in the build and install export sets.

TODO: Documentation

* file-set-build-export:
  cmExportBuildFileGenerator: handle genex-wrapped source paths
  cmInstallCommand: tweak error message

This allows for new fileset types to be added more easily by factoring
out the declarative information into a structure.

With new types being proposed for C++ modules, requiring filesets to be
of the right type is now pertinent. No tests can be added yet as only
`HEADERS` is supported right now.

This avoids having to copy the `std::string` overload.

Previously a fileset with `$<$<CONFIG:Debug>:some_file>` would show up
as-is (with escaping) in the build directory export. Instead, evaluate
all fileset entries as generator expressions and list them as they are
similar to the installation information.

Not all filesets need to be installed; just those that are visible on
the target's interface. Clarify the error message.
