* Update paste and drop proposals
Reworks the document paste and drop API proposals. Main highlights:
- Align more with code action api
- Allow a single paste provider to return multiple edits
- Allow resolving applied edits lazily
- Switch from using ids to scoped kinds like used for code actions
* Adding paste context
* Add context
* Update test
These tests fail occasionally in CI, seemingly only on linux. This tries to fix this by:
- Adding retries
- Switching back to use `teardown` to disposed of things. `usingDisposable` may not clean up properly if the test times out
This fixes the range extensions get when copying an empty selection. As part of this, I've also:
- Added tests for this change
- Made the paste parts of the api optional. This is useful when a test provider only wants to add data on copy
