Remaining work to get 'Background Wait Indicator' sufficient for most of Roslyn, and ready for Platform adoption.

[CyrusNajmabadi]

So far, our experience with the new background work indicator (BWI) has been positive. The API is a near drop in for the existing threaded-wait-dialog (TWD) API and allows a much more lightweight, non-blocking, in-situ UI for letting the user know what's going on.

@ryzngard and I have been talking about what remains to make this a sufficient system for the 90% case for Roslyn, as well as being capable and proven out enough to then move to 'platform' as a general VS facility.

The remaining items are as follows:

1. The UI shoudl be able to show progress. This is supported in the API already, and is really needed for very long running operations to let the user know that things are actually progressing. This is def necessary if we want to move 'code action - fix all' over to this as the operation time can sometimes be minutes. This is acceptable when you at least can see that it's moving forward, but not at all ok if the user can't see anything happening while they wait.
2. The UI needs to be accessible. This is mandatory for anything we do.
3. The UI should provide a good experience around large-scale "global" operations. Right now the UI shows up in the editor, meaning that if you are making a global operation and switch tabs it will either continue running (without any indication that is happening), or it has to cancel. Similarly, if the user edits at all, the operation will instantly cancel, without giving them a chance to not do that. To make this better, we should likely have varying UIs for this feature depending on the flags the user passes in. For these global operations we should likely place the UI in the VS chrome itself so that it is always visible even while the user navigates around. We should also capture edits in that time and notify the user that editing would cancel and ask them if they want to proceed with the edit or not.
4. The UI needs to be interactive/responsive even if the VS UI thread is blocked (just like the TWD is). However, this should likely be done by the platform, not us (reusing the infrastructure pieces the TWD already has).
5. Allow this UI to work without a text-editor to show hte UI. We can consider using the VS task progress list:

• Use background work indicator for Go To Definition #69389
• Use background work indicator for Go To Implementation #69390

@ryzngard @vatsalyaagrawal @mikadumont For visibility. I recommend front loading the design portion of this in the end of 17.3, and then doing the impl side of it in 17.4.

The UI needs to be interactive/responsive even if the VS UI thread is blocked (just like the TWD is).

This is going to be nearly impossible for us to complete. The TWD is implemented as a separate process which then shows over the main VS window (so it has its own rendering loop). We can safely defer this to the editor.

That's why it's in teh bucket of:
