Add possibility to remove invited user from workspace chat and add possibility for invited user to leave from the workspace chat

[waterim]

Problem:

Right now there are no possibilities to leave or be removed from the workspace chats. But there should be a possibility for INVITED members to be removed or to remove themself(leave) from the workspaces chats.

Solution:

As discussed in the main issue, we would like to add this possibility to remove invited users from the workspace chats and also add possibility to leave workspace chats.

1. For all invited members except automatically added [Admin, Default member] we need to add a Leave button from the workspace chats in the similar way as we are doing Invite/Remove
2. Also we need to add possibility for automatically added default users [Admin, Default member] to remove invited members/guests in the similar way we are removing in Workspaces itself.

IMPORTANT details for workspace chats:

1. To understand more regarding automatically added users read this comment
2. What we want to achieve: comment

I merged all this into #35391; closing this one.

@quinthar I think different issues are better as leaving for workspace/policy expense chat workflow requires a bit of UI/UX update and calling API commands that can be worked by an external contributor

Closing in favor of #35286
