go/grid-migration-preview
With this change, we can see actual grid migration in wallpaper preview.
The approach here: we use a tmp table (favorites_preview) here specifically for this preview (to write off the migration results), and load from this tmp table workspace items if migration is necessary and successful. Otherwise, we load from the current workspace.
UPDATED: this change should be completely compatible with the new multi-db grid migration algorithm. Here is why
1. In LauncherPreviewRender#renderScreenShot, I added a check to decide which grid migration preview method we should call. Once v2 preview method is implemented, it should be integrated with other parts of this change perfectly (the reason will be mentioned below).
2. While we have multiple DBs, mOpenHelper in LauncherProvider always points to the current db we are using. Queries using CONTENT_URI is routed to whatever DB mOpenHelper points to, so it works perfectly to directly operate on CONTENT_URI even when we use multi-db underneath the hood.
3. With 1 and 2 mentioned, I believe in order for this preview change to support multi-db, we only need to implement the V2 grid migration algorithm. Because most of what we are doing in this change is wrapped in GridSizeMigrationTask, it's perfectly safeguarded.

With this change, we can also render folders in preview. It's built on top of part 1.
Test: Go to grid options, choose a different grid option, and see user's workspace rendered in the preview

This change takes care of icon rendering. Further work still needs to be done for folders and widgets.

This will allow subclassing BitmapInfo to support custom icon/dynamic
icons which can be loaded on the background thread instead of going
through IconFactory which runs on UiThread
