Excludes remote channels from channel search (#28708)

* Excludes remote channels from channel search

This is done through a new body parameter in the SearchAllChannels
endpoint that allows to search for local only channels, which are
either channels that are shared but marked as homed locally, or
channels that are not shared at all.

* fix lint

* Fix tests
