<!-- PR description-->
Group export sanity test is failing because we added conversations to `sel.AllData()`. But we don't have export support for conversations yet.
Adding conv selector to exclude so that it doesn't fail exports for groups libraries and channels. This is a short term change, and will be removed once we have export support https://github.com/alcionai/corso/issues/4822

various tidbits of data cleanup before moving forward with adding export behavior to groups.
* move duplicate collections mocks into data/mock
* move the export collection struct into pkg/export (to prevent future duplicates in the next PR)
* rename export.Collection to Collectioner, because it's an interface.
* some other non-logic rearrangement
