GenEx: Add support for custom transitive compile properties

Browse Source 
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:...>`.
