Brad King 0f688386ea Modules: Drop redundant check logging to CMakeOutput.log and CMakeError.log
`try_compile` and `try_run` now automatically log checks using them to
`CMakeConfigureLog.yaml`.

Add `LOG_DESCRIPTION` arguments to some `try_compile` calls to
replace the description previously written to the old logs.
