When using the directed vendor snapshot, the build fails because soong
fails to find some variants of the modules that have been excluded
from VENDOR_SNAPSHOT_MODULES, even though those modules are not going
to be used by the build.
The solution implemented here is to generate fake versions of those
modules (empty files) and include them in the generated Android.bp,
so that soong finds the modules, even though trying to use them would
fail.

Propgate the Android.mk suffix from source modules into the snapshot so
that it can be used for the prebuilt modules.

Snapshots storead global sets of modules that should be replaced with
vendor snapshot modules. Move the data instead to a vendor_snapshot
or recovery_snapshot module type that depends on all the modules in
the snapshot, and then have modules that should use the snaphsot
depend on it to query for the set of modules that should be replaced.
