Move globbing to Blueprint

Move Soong's globbing-with-dependencies support into Blueprint so it can
be used for subdirs= lines in Android.bp files.

Blueprint has a slight change in behavior around subname= lines, it now
always uses the subname and doesn't fall back to Blueprints.  To support
the Blueprints files in build/blueprint, use them directly with build=.

Test: build, add source file that matches glob, rebuild
