Prepare for Fabric native (#2050)

* Implement fabric native path

* Fix default values to work with current fabric clients

* Fix Fabric native mode

* Fix unit test

* export Fabric context

* Dynamically close Home tab for Mirrored databases in Fabric rather than conditional init (which doesn't work for Native)

* For Fabric native, don't show "Delete Database" in context menu and reading databases should return the database from the context.

* Update to V3 messaging

* For data plane operations, skip ARM for Fabric native. Refine the tests for fabric to make the distinction between mirrored key, mirrored AAD and native. Fix FabricUtil to strict compile.

* Add support for refreshing access tokens

* Buf fix: don't wait for refresh is async

* Fix format

* Fix strict compile issue
