854eba0c53 target_sources: Improve error message for CXX_MODULES on INTERFACE libraries

We support non-compiled `SOURCES` on `INTERFACE` libraries, and also
support `CXX_MODULES` on *imported* `INTERFACE` libraries (via synthetic
targets that compile module interface units). However, we do not
support `CXX_MODULES` on non-imported `INTERFACE` libraries because
there is no place to hold module interface unit's object files for their
module initializers. Previously this was not explicitly rejected, and
so was diagnosed only by "CMake Internal Error" messages due to
assumption violations in the implementation.
Fixes: #26524

Previously, only `export()` calls in the same directory were noticed.
Also add a test that exports in a different directory than the target
itself resides in.

Also update the `modules-json-file` test to account for the fact that
`CXXModules.json` is not updated for timestamp-only rebuild triggers.
See: #25511
`cmSourceFile::GetFullPath()` performs a `CollapseFullPath` before
storing the path. Match this behavior when looking up paths from the
source file set constructions.
Fixes: #25614
Include the name of the `EXPORT` in the filename when generating export
information for C++ modules. This allows the same directory to be used
for multiple sets of C++ module-using targets.
For `export(TARGETS)` uses, generate a name based on the hash of the
concatenation of the target names involved with the `export()` call.
Fixes: #25609
Compute link information for all C++ targets which support
modules instead of just those which may provide modules, as
they may import modules as well. This captures `OBJECT` libraries using modules
which otherwise do not have link steps.

Previously CMake may generate incomplete transitive requirements in
CMakeFiles/<target>.dir/CXXModules.json and therefore in module mapper
for compiler, when source files were listed in CMakeList.txt in a
certain order.
This commit fixes the problem by correctly tracking unfinished
transitive requirements computation of module units.
There have been a simple circular test case whose circular dependency
was reported by build system. Now with this correct implementation it's
reported by CMake generating module mappers.
Add two test cases for transitive requirements computation, one with
adding source files in hardcoded order, and the other in randomized
order.
Fixes: #25465
