[CFI] Add an "exposed" filter for workspace when a user is a member of several workspaces

[JmillsExpensify]

We currently have several "exposed" filter open the Reports page results, like so.

Based on feedback from our members, we'd like to add a new exposed filter for Workspace. It should work like this:

• The exposed Workspace filter only appears if a user is a member of 2 or more workspaces
• The exposed Workspace filter always appears farthest to the right (after From)
• Everything else about the exposed filter works like other exposed filters

I think that should cover it, though let me know if I'm missing anything!
