Add support for prebuilt AARs.
- You can give a .aar as source file to a prebuilt static Java library
module. The build system will set up dependencies and rules to extract
classes.jar and other resource files.
- To build against a prebuilt AAR module, use:
LOCAL_STATIC_JAVA_AAR_LIBRARIES := <module names of aar prebuilt AARs>
The build system will set up rules to merge the library's
AndroidManifest.xml with the main AndroidManifest.xml, add the AAR's
resource dirs and link/merge the AAR's classes.jar.
