A couple of fixes in rapids-logger usage

[vyasr]

Description

This PR has two fixes:

• Since we're pinning to a commit, a shallow clone will start failing as soon as HEAD gets bumped on the main branch (which will happen next when cuml/raft logging features are merged). We need to stop using shallow clones.
• The CMake code for setting the default logging levels was setting the wrong macro name.

Checklist

• I am familiar with the Contributing Guidelines.
• New or existing tests cover these changes.
• The documentation is up to date with these changes.

Does CPM clone first and then check out the tag? I would expect it to use git clone -b, in which case this wouldn't be needed, but if that's how they're doing it then I see why it would be an issue.

CPM isn't doing anything at the git clone stage other than invoking FetchContent. I can replicate the behavior locally if I change my cudf to use commit f9b007ae30f924de2dca8c585334f0d55331d0b8 instead of the latest head c510947ae9d3a67530cfe3e5eaccb5a3b8ea0e55, see the traceback below. I don't think there's anything unexpected here, this is how ExternalProject is documented to work:

If GIT_SHALLOW is enabled then GIT_TAG works only with branch names and tags. A commit hash is not allowed.
