Instead, use state descriptions for the varying parts, which means that
there is not an explosion of channel types for every single Home Assistant
channel, which can cause performance issues if you have a lot of
devices/channels

This has two important impacts, and one not-as-important-but-still-
beneficial impact:
 * ThingTypes are not created for Things that are never actually
   created, but only discovered, reducing bloat.
 * Avoids warnings about things types not being in the registry
 * Thing IDs end up like
   mqtt:homeassistant:broker:mydevice instead of
   mqtt:homeassistant_mydevice:broker:mydevice

Note that already-created things will maintain their original ID,
and it's only new things created from auto-discovery that will have
the new, shorter thing IDs.

This is triggered by a property only set by discovery, so will only apply
to newly created things.

Channel groups are now named after simply the component type and object_id,
if possible, and without additional encoding, instead off encoding the
unique_id. Most devices will encode the component type and device identifiers
into the unique_id, and of arbitrary format, so it is far more complicated
than necessary, when a channel group is already only within the scope of
the thing/device.

Many component types that can only ever have one channel (button, switch,
sensor, select, scene, etc.) will not be in a channel group anymore. In this
case their channel id is what their group id would have been, without the
repetitiveness of "sensor_<unique_id>#sensor".

Includes both homie and homeassistant dynamic things.
It also fixes all ordering issues in both bindings in order to
be consistent in how types are persisted:
 * For Homie, Nodes (channel groups) and Properties (channels)
   are ordered in the way they are defined in $nodes and $properties
 * For Home Assistant, Components are ordered by label. This
   includes both single channel components that are not in a channel
   group, as well as channel groups. We also ensure that on the
   Thing itself non-grouped channels consistently sort before grouped
   channels.
