Move manifest generation logic into static_java_library.mk

Previously a manifest file would be generated for static_java_library.mk
and package_internal.mk. For pacakge_internal.mk, this would cause
cryptic errors like b/188612215#2

With this CL, a manifest file would only be generated for java_library
with need_compile_res == true. The advantages are
1. No redundant generation for java_library with need_compile_res == false
(i.e. modules that do not require aapt2)
2. Force devs to provide manifest for android_app, and not silently
generating one for them
