Teach the `$<TARGET_PROPERTY:...>` generator expression to check for a
new `TRANSITIVE_COMPILE_PROPERTIES` property in the target's link
closure to enable transitive evaluation of named properties through
the link closure, excluding entries guarded by `$<LINK_ONLY:...>`.
Issue: #20416
Previously this method always returned the closure for compile-only
usage requirements. Add an option to get the closure for linking, which
pierces `$<LINK_ONLY>`.
