- Creates a backup table `hybrid_hotseat_restore` and copies current workspace layout before hotseat migration
- restores to back up when user turns off suggestions and launcher receives empty predicted items
- deletes hybrid_hotseat_restore table if there's a layout change

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.

Removed the code to handle table copying across dbs. We don't really need this since per ag/10298497, we can just copy db files directly.

We'll have a db for each grid option and a db for back up / restore.
TODO(pinyaoting): support back up / restore using the new infrastructure, particularly calls to GridBackupTable should use different DBs when the feature flag (NEW_GRID_MIGRATION_ALGORITHM) is on.

(see go/play-launcher-plan-launcher-implementation)
1. When Launcher launches for the first time, creates a backup
of the workspace before sanitizing db entries.
2. Creates a new path in LauncherProvider that triggers workspace
restore using last stable db entry of the same grid size.
3. When restore from backup created this way, the table will be
sanitized afterward.
Test:
1. apply on master, build & refresh on physical device
2. factory reset, go through SuW and perform restore
3. exit SuW without signing into Work Profile
4. run following commands in console
adb root
adb remount
adb pull
/data/data/com.google.android.apps.nexuslauncher/databases/launcher.db
sqlite3 ./launcher.db
.tables
SELECT * FROM favorites_bakup;

Favorites table is copied as a separate table name during the first grid migration.
On subsequent migrations this backup table is used if it exists, otherwise new
backup is created. The backup table is also removed if there is any insert or
delete operation on the db (outside of the migration operation itself).
