- Reset next X when finding the next available space for placement
- Cache icons by screen id in a map so that we don't need to load it each time
- Update tests accordingly

- Init KEY_MIGRATION_SRC_WORKSPACE_SIZE and KEY_MIGRATION_SRC_HOTSEAT_COUNT
- Load default workspace only when default db is created, not when peeking into dbs of other grid options during grid preview / migration

The focus of ag/10346770 is around the actual algorithm, while in the meantime our preview logic has changed during the code review of ag/10100264.
GridSizeMigrationTaskV2 addresses both cases, the difference being preview passes in constructed IDP while actual migration uses IDP from the current Context.
When doing actual migration, we call METHOD_UPDATE_CURRENT_OPEN_HELPER to update the current db helper and copy the favorites table from the previous db into the current db in favorites_tmp table. Then we do migration from there.
When calculating preview, I added METHOD_PREP_FOR_PREVIEW in this change to copy the favorites table from the intended grid setting to the current grid setting in favorites_preview table. Then we calculate migration from the current favorites table to favorites_preview table and save into favorites_preview table.

When changing grid from option 1 to option 2, we calculate the diff and add the icons that are in option 1 but not option 2, to option 2's workspace, according to the reading order.

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.

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.
