Subject: [PATCH 1/2] Showing wider header/status bar in shade on large screen
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Note: Because this change is already huge, I’ll do proper renaming of split shade header to large screen header in the follow-up CL.

- introducing new config flag: config_use_large_screen_shade_header and using it to determine which header should be visible
- Several adjustments to paddings and margins and how they are calculated on the fly, mostly from notification scrim and motion perspective. Recalculating scrim bounds relative to view bounds
- cleaning Utils.java which got very wide-reaching over time. Some things were not used at all and some could be moved. I extracted some functions to two separate utils classes (also open to better ideas): QSUtils and LargeScreenUtils. Not ideal but at least better than one big Util.

Fixes: 222472794
Test: expand shade on large screen device in portrait and see one row QS header taking full width of the screen
Test: NotificationPanelViewControllerTest + NotificationQSContainerControllerTest
