Refactor Tuya EnchantedDevice to use custom configuration

[TheJulianJES]

Proposed change

This PR refactors the Tuya spell code in EnchantedDevice to use the apply_custom_configuration hook in BaseCustomDevice (introduced in recent zha/zigpy versions).

This allows us to remove the workarounds of "enchantable" clusters where bind() was hijacked and called the Tuya spells.
With this PR, we can call the Tuya spell code way easier (and slightly earlier).

A bunch of now irrelevant documentation and tests are also removed. The tests can likely be reduced a bit more in future PRs, as we no longer need to test that every device/quirk correctly casts the spell, but it also doesn't hurt anything.
So, if we want to change the "spell tests" further, I'd push that to a future PR.

Additional information

Requires:

• Also apply custom configuration to v1 quirks zha#231
• Apply custom quirks config before configuring cluster handlers zha#239 (kind of)

Checklist

• The changes are tested and work correctly
• pre-commit checks pass / the code has been formatted using Black
• Tests have been added to verify that the new code works
