Remove cc.moduleContext override of android.ModuleContext.*Specific

Overriding android.ModuleContext's implementations of *Specific()
methods in cc.moduleContext and then passing that back to
android.PathForModuleInstall to affect the install path causes
problems if android.ModuleBase.GenerateBuildActions also tries
to call android.PathForModuleInstall directly with the
android.ModuleContext as it gets a different result.

Add InstallIn* methods to the android.Module interface, implement
default versions in android.ModuleBase, and override them in
cc.Module and rust.Module.  Use them in android.PathsForModuleInstall
to allow the module to customize the behavior directly.
