[tado] Create channels dynamically depending on device capabilities

[andrewfg]

Background

Analog to #13271 and #13275

Currently a tado zone thing can be either a central heating or an a/c device. And currently all things are created statically with the superset of all channels for all possible functions of heating and a/c devices.

So for example 'fanSpeed' and 'fanSwing' channels are statically created for a heating radiator device. Which makes no sense, and could be confusing for users.

Proposed Solution

Depending on the device 'type' and its published 'capabilities', the appropriate channels will be created dynamically.
