* Allow Just-in-Time platform setup for mqtt
* Only forward the setup of new platforms
* Fix new platforms being setup at reload + test
* Revert not related changes
* Remove unused partial
* Address comments, only import plaforms if needed
* Apply suggestions from code review
* Add multipl platform discovery test
* Improve test
* Use a lock per platform
Use async_forward_entry_setups so platforms can be loaded in a single
executor job instead of many:
Currently they all have to create a new job because it did not use
async_forward_entry_setups
