Fix: PathsForModuleSrc does not work for a replaced dependency

PathsForModuleSrc does not work if a source module is replaced with a
prebuilt module. This is because the function uses GetDirectDepWithTag
with the name of the original source module. Since the dependency is
replaced and the prebuilt module has the name "prebuilt_<name>", the
search always fails.

Fixing this by re-implementing GetDirectDep* functions inside Soong
using VisitDirectDep.
