- 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functionality is superseded.
Updated the logic for setting the FMT_USE_CMAKE_MODULE flag to check the
versions for Ninja and MSVC according the CMAKE Documents and setting
the FMT_MODULE flag based on this

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.

* Avoid a space in the UDL definition except on GCC before 4.9
Clang 18 has grown a warning about the space being deprecated which
is enabled by default in their nightly binaries. However GCC before 4.9
will reject the UDL definition unless there is a space there, so we need
to keep the space conditionally for it.
* Remove UDLs on GCC before 4.9 to simplify things
GCC before 4.9 rejects the syntax that is now
rejected on more modern compilers.
* Disable compile-error-test on GCC < 4.9
This avoids the UDL tests failing as GCC < 4.9 can not parse UDLs
without a space, but the space is malformed in modern compilers.
* use the standard `test-main.cc` component instead of injected test infrastructure sources
* undo now obsolete commit `00235d8a` from July 2021
* Clang cannot import user-defined literals as it seems -> disable test
* Clang emits duplicate, non-mergeable copies of `detail::buffer`'s vtable, causing linker errors -> disable test
It disables entire branch of tests declaration unconditionally because CXX_STANDARD
is not defined there. But even we use CMAKE_CXX_STANDARD here, these tests should
not be disabled with standard >= C++20.
* do this in _some_ tests to improve test coverage and catch possible problems due to that
* fix invalid export of `static constexpr` constant
* fix msvc warnings about unreachable code in high warning levels
