AIDEGen: Collect the classes.jar of the prebuilt modules into module-info.json

Current information is not enough if the prebuilt modules are depend on
AAR libs Therefore, AIDEGen has to collect the classes.jar of the
prebuilt modules from build system.

Build module-info.json without this change:
Build time: 1m55.001s
File size: 14,918,354 Bytes

Build module-info.json with this change:
Build time: 1m56.292s
File size: 15,577,031 Bytes

Bug: 132768299
Test: 1. Checkout the internal master branch
      2. Patch this CL
      3. m -j out/target/product/generic_x86_64/module-info.json
      4. Open the module-info.json
      5. For verifying soong_java_prebuilt.mk, check the classes.jar of
         module prebuilt-google-play-* exists.
         e.g.
         "prebuilt-google-play-...": {
              ...
              "classes_jar": [
	      	"out/target/common/obj/JAVA_LIBRARIES/
		 prebuilt-google-..._intermediates/classes.jar"
	      ]
         }
      5. For verifying java_prebuilt_internal.mk, check the classes.jar
         of module ink exists.
         e.g.
	 "ink": {
	     ...
	     "classes_jar": [
	     	"out/target/common/obj/JAVA_LIBRARIES/ink_intermediates/
		 classes.jar"
	     ]
	 }
