DEV: Make composer-uppy-upload mixin more extensible (#14138)
This mixin needs to be shared between the composer and composer-like
user interfaces. This commit makes it so the events and the underlying
data model is configurable by the component extending the ComposerUploadUppy
mixin.

Also removes two MessageBus unsubscribe calls which were unnecessary.
