… libcuml conda host dependencies (rapidsai#6071)

Contributes to rapidsai/build-planning#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 rapidsai#6071 (comment))

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.
