Update fmt (to 11.0.2) and spdlog (to 1.14.1), add those libraries to libcuml conda host dependencies

[jameslamb]

Description

Contributes to https://github.com/rapidsai/build-planning/issues/56

• updates fmt and spdlog to newer versions, to match the rest of RAPIDS
• adds fmt and spdlog to host: dependencies for libcuml conda packages (see https://github.com/rapidsai/cuml/pull/6071#discussion_r1771772139)

Now that most of conda-forge has been updated to fmt >=11.0.1,<12 and spdlog>=1.14.1,<1.15 (https://github.com/rapidsai/build-planning/issues/56#issuecomment-2334281452), 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.
