Remove SDK dep from module_lib_api

This had the consequence of making two large metalava invocations
run in sequence rather than parallell.

For now, add back the dependency on framework-all instead. Building
framework-all should be a lot faster than the sdk stubs.

Also move the module stubs dep from framework_defaults to
framework-minus-apex. framework-all does not need this dep.
