Support customizing behavior around sourceOrOutputDependencyTag

Previously, modules customized behavior around the handling of
sourceOrOutputDependencyTag by comparing them to android.SourceDepTag
and retrieving the module using something like this:
    ctx.GetDirectDepWithTag(m, android.SourceDepTag)

The problem with that is it does not allow an output tag to be
specified and does not handle fully qualified names properly.

This adds the following:
* IsSourceDepTag and IsSourceDepTagWithOutputTag to check whether a
  blueprint.DependencyTag is a sourceOrOutputDependencyTag. The latter
  also checks that it has the correct output tag.
* GetModuleFromPathDep(ctx, moduleName, outputTag) as a replacement for
  ctx.GetDirectDepWithTag(m, android.SourceDepTag).

Replaces usages of:
* t == SourceDepTag with IsSourceDepTagWithOutputTag(t, "")
* ctx.GetDirectDepWithTag(m, android.SourceDepTag) with
  GetModuleFromPathDep(ctx, m, "")

It also deprecates the following:
* android.SourcDepTag - as a follow up change needs to modify the
  sourceOrOutputDependencyTag will make this useless.
* ExpandSources, ExpandsSources - copies existing deprecated messages
  from the implementation to the interface so that they can be seen
  by users of that interface.
