Paul Duffin 91b883d541 java_sdk_library - replace .docs suffix with .stubs.source
Previously, the .docs suffix was used for droidstubs internal modules
that generate the stubs source. The name was confusing so this change
replaces the suffix with .stubs.source to clarify the purpose of those
modules.

Bug: 148080325
Test: m droid
