PLT-5049 (Webapp) New Channel Members UI. (#5036)

This replaces the existing Channel Members UI with one based on the Team
Members UI, so that either a button, a role or a role with a menu can be
displayed.

Basic logic for which actions and roles are displayed is implemented,
although this doesn't change behaviour or functionality at all, as that
will come in later PRs. It does, however, add code to fetch the
ChannelMember objects as that is necessary to provide the full set of
actions and roles as intended.
