settings: Rename helper function to check who can edit topics.

This commit renames "can_edit_topic_of_any_message" function
in models.py to "can_move_messages_to_another_topic" and
"user_can_edit_topic_of_any_message" function in settings_data.js
to "user_can_move_messages_to_another_topic".

This change is done since topic editing permission does not
depend on message sender now and messages are considered same
irrespective of whether the user who is editing the topic had sent
the message or not. This also makes the naming consistent with
what we use for the label of this setting in webapp and how we
describe this action in help documentation.
