enable fmt_module tests by updating module-test.cc ( #4702 )
...
- Update g++ module testing to use g++ version 15 instead of 14.
The module support in version 14 isn't very stable and the module
testing was not working due to unresolved locale symbols.
- Update CI for linux and macos to add verbosity so its consistent with
windows.
- Refactor test/CMakeLists.txt to enable testing for modules
- The tests in `module-test.cc` seem to not have been updated in some
time despite changes in the main library.
- Wide String versions of several tests appear to be deprecated so have
been removed.
- Refactored tests related to `fmt::format_args` that now requires lvalue
references as opposed to direct values.
- Remove the none-working code identified in the `module-test.cc` file
while updating.

* Add Separate CMake Target for C++20 Modules
In the same vein as there is the `fmt::fmt-header-only`, `fmt::fmt` and
`fmt::fmt_c` targets, I propose the addition of a new target
`fmt::fmt-module` which will be for the compilation of the FMT_MODULE
library option.
The new target will have the properties requried for Compiling,
Installing and using the C++20 functionality in CMake
The `add_module_library` function is marked as deprecated as its
functionality is superseded.

Fixed the test/CMakeLists.txt file which used the FMT_MODULE flag to
separate the module and non-module library testing, in particular
disableing the module version.
The module testing still needs to be fixed, but the expected behavior of
testing the non-modular version is working.

Handle allocator propagation in basic_memory_buffer::move, Fix #4487 ( #4490 )
...
* Handle allocator propagation in basic_memory_buffer::move
Update `basic_memory_buffer::move` to respect `propagate_on_container_move_assignment`allocator trait.
If the allocator should not propagate and differs from the target's allocator,
fallback to copying the buffer instead of transferring ownership.
This avoids potential allocator mismatch issues and ensures exception safety.
* Add test cases for the updated move ctor
- Added two test cases `move_ctor_inline_buffer_non_propagating` and `move_ctor_dynamic_buffer_non_propagating`
- Added `PropageteOnMove` template parameter to `allocator_ref` class to be compatible with the old test cases
- `allocator_ref` now implements `!=` and `==` operators
