Brad King ad2b3a32d1 Genex: Optimize build setting TARGET_PROPERTY evaluation ...

For each build setting property (such as `COMPILE_DEFINITIONS` or
`INCLUDE_DIRECTORIES`), the value of `$<TARGET_PROPERTY:target,prop>`
includes the values of the corresponding `INTERFACE_*` usage requirement
property from the transitive closure of link libraries of the target.

Previously we computed this by constructing a generator expression
string like `$<TARGET_PROPERTY:lib,INTERFACE_COMPILE_DEFINITIONS>` and
recursively evaluating it with the generator expression engine.  Avoid
the string construction and parsing by using the dedicated evaluation
method `cmGeneratorTarget::EvaluateInterfaceProperty`.

Issue: #18964, #18965
