GenEx: Add support for custom transitive link properties

Teach the `$<TARGET_PROPERTY:...>` generator expression to check for a
new `TRANSITIVE_LINK_PROPERTIES` property in the target's link
closure to enable transitive evaluation of named properties through
the link closure, including entries guarded by `$<LINK_ONLY:...>`.

Fixes: #20416
