Special-case Soong finder to look in out/api_surfaces
Add a new argument in soong_ui that will be used to gate this behavior.
This approach is expected to solve incrementality issues in multi-tree.
As part of soong's bootstrap process, all source dirs are added to deps
of out/soong/build.ninja (via globs). Since multitree_build writes to the
"source" api_surfaces directory, it changes its mtime and causes a
recompilation of out/soong/build.ninja in the subsequent invocation.
Test: TH (for single-tree)
Test: Inspected ninja files (for multi-tree)
(Run a full build)
