Use device_one_time_keys_count to match MSC3202 (#14565)

* Use `device_one_time_keys_count` to match MSC3202 Rename the `device_one_time_key_counts` key in responses to `device_one_time_keys_count` to match the name specified by MSC3202. Also change related variable/class names for consistency. Signed-off-by: Andrew Ferrazzutti <[email protected]> * Update changelog.d/14565.misc * Revert name change for `one_time_key_counts` key as this is a different key altogether from `device_one_time_keys_count`, which is used for `/sync` instead of appservice transactions.
