file: Change REMOVE to ignore empty names
Previously code like
file(REMOVE_RECURSE "${accidentally_missing_variable}")
treated the empty string as a relative path with respect to the
current directory and removed its contents. Change this behavior
to ignore the empty string with a warning instead.
Normally such behavior changes are done with a policy, but in this case
such code is likely a real bug in project code that can delete data.
Fixes: #19274
