HideFromMake in `apexTransitionMutator` should respect special cases

At ToT, platform variants of modules are hidden from make, unless the module
has `//apex_available:platform` in its Android.bp file. However, there
are special cases which always require the platform variant to be
visible to make - e.g. bootstrap bionic libraries.

`markPlatformAvailability` handles these special cases. This CL updates
the subsequent apexTransitionMutator to hide the platform variant when
module.NotAvailableForPlatform is true in addition to the existing
module type specific `AvailableFor` check
