Subject: [PATCH] Tune Overview size according to VisD

- Removed modalTransformY as overview actions no longer need to move in modal view
- Moved row spacing and page spacing to DeviceProfile
- Added several tablet / orientation specific DeviceProfile params

Bug: 194194694
Test: Manual
Change-Id: Id5435e7f6fc1b6fb7c0e55e55fa240cf84c4d6da
