Added HomeKit fan speed

Description:

Added support for HomeKit fan speed.

I wasn't sure about the cast to string for the fan speed, but it seems fan components hold speed as a string.

Checklist:

• The code change is tested and works locally.
• Local tests pass with tox. Your PR cannot be merged unless tests pass

Unfortunately the solution isn't that strait forward. That's the reson why it was excluded from #14351

I understand. It would be nice if we could add this as a stopgap though, some fan speed would be better than no fan speed support at all, no?

In this case sadly no. Nearly every fan platform does it differently, so users will only complain why it doesn't work. We have to fix the speed settings first.
