Specify `stubs_type` property in java_api_library modules

With the effort to support non-"everything" stubs generation from api
signature files, https://r.android.com/2977092 enforces all
java_api_library modules to specify the `stubs_type` property. In order
to accustom to this enforcement, this change specifies the `stubs_type`
property as "everything" to all bp-defined "everything" stubs generating
java_api_library modules.
