Fix the evaluation of per-config COMPILE_DEFINITIONS (#14037)

The API for retrieving per-config COMPILE_DEFINITIONS has long
existed because of the COMPILE_DEFINITIONS_<CONFIG> style
properties. Ensure that the provided configuration being generated
is also used to evaluate the generator expressions
in cmTarget::GetCompileDefinitions.

Both the generic COMPILE_DEFINITIONS and the config-specific
variant need to be evaluated with the requested configuration. This
has the side-effect that the COMPILE_DEFINITIONS does not need to
be additionally evaluated with no configuration, so the callers can
be cleaned up a bit too.
