When extracting dependencies from properties tagged with
`android:"path"`, only look at the general property structs
and not the arch-specific ones. The necessary arch-specific
values will be appended into the general property structs.

Add a mutator pass after DepsMutator that visits every property
struct in every module looking for properties that have a tag
`android:"path"`, and automatically add a SourceDepTag dependency
on any module references (":module-name") found. Uses a cache to
store the mapping of property struct type to locations of
properties with the tag.
