Update fmt (to 11.0.2) and spdlog (to 1.14.1).

Description

Replaces #15603

Contributes to:

• Treat clobber warnings as errors for conda builds build-planning#54
• update fmt and spdlog across RAPIDS build-planning#56
• [FEA] rapids_cpm_spdlog generate correct build config support rapids-cmake#387

Now that most of conda-forge has been updated to fmt >=11.0.1,<12 and spdlog>=1.14.1,<1.15 (rapidsai/build-planning#56 (comment)), we're attempting to upgrade RAPIDS to similar versions of those libraries.

This improves the likelihood that RAPIDS will be installable alongside newer versions of its
dependencies and complementary packages on conda-forge.

Notes for Reviewers

This PR is testing changes made in rapidsai/rapids-cmake#689.
It shouldn't be merged until those rapids-cmake changes are merged and any testing-specific details have been removed.

I've paired removing the spdlog export here with adding this over in cpp/CMakeLists.txt:

target_linked_libraries(cudf PRIVATE spdlog::spdlog_header_only)

Without that, the pip devcontainer build here fails like this while building the pylibcudf wheel:

CMake Error at /home/coder/.local/share/venvs/rapids/lib/python3.10/site-packages/cmake/data/share/cmake-3.30/Modules/CMakeFindDependencyMacro.cmake:76 (find_package):
    By not providing "Findspdlog.cmake" in CMAKE_MODULE_PATH this project has
    asked CMake to find a package configuration file provided by "spdlog", but
    CMake did not find one.
    
    Could not find a package configuration file provided by "spdlog" with any
    of the following names:
    
        spdlogConfig.cmake
        spdlog-config.cmake
    
    Add the installation prefix of "spdlog" to CMAKE_PREFIX_PATH or set
    "spdlog_DIR" to a directory containing one of the above files.  If "spdlog"
    provides a separate development package or SDK, be sure it has been
    installed.

I think because in devcontainers, libcudf.so is built outside of wheel builds, which means that this condition is hit:

cudf/python/libcudf/CMakeLists.txt

Lines 29 to 31 in a0c6fc8

	if(cudf_FOUND)
	return()
	endif()

And then later code that makes spdlog available isn't run.

This seems plausible to me but I'd like a confirmation from a CMake expert. @vyasr or @KyleFromNVIDIA?

Looks good to me, but maybe a second eye on the CMake changes would be helpful to confirm that we're going the right way.
