Bump spdlog to 1.11, add fmt as dependency for spdlog (#368)

Bumps spdlog to 1.11.0 and adds `fmt` as a dependency of spdlog and sets the `SPDLOG_FMT_EXTERNAL_HO` cmake option for spdlog. Happy to change that to be controlled by an argument to the `rapids_cpm_spdlog` function if desired. I believe the existing testing should cover the changes made here as the `spdlog` and `rmm` related tests were failing until adding `fmt` to the `spdlog` `BUILD_EXPORT_SET` and `INSTALL_EXPORT_SET`.

+
+  Spdlog depends on the fmt library and offers multiple ways of handling this dependency when spdlog is built. This
+  option only controls the behavior when spdlog is fetched and built, NOT when an installed spdlog is found on the
+  system.
+
+  This option can be set to: `BUNDLED`, `EXTERNAL_FMT`, `EXTERNAL_FMT_HO`, or `STD_FORMAT`. If set to
+  `BUNDLED`, then spdlog will use its own bundled version of fmt. If set to `EXTERNAL_FMT` then spdlog will use the
+  `fmt::fmt` target and be linked with the fmt library. If set to `EXTERNAL_FMT_HO` then spdlog will use the
+  `fmt::fmt-header-only` target and be linked with a header only fmt library. If set to `STD_FORMAT` then spdlog
+  will use `std::format` instead of the fmt library.
+
+  Defaults to `EXTERNAL_FMT_HO`.
