Using HardwareRenderer to draw omnibar instead of Canvas API

This CL is an attempt to fix crashes caused by migrating the
renderer to hardware accelerated drawing, replacing the
Canvas API calls with the HardwareRenderer call, the gains
in drawing time observed after the migration are still
observed with the new API.

This is controlled by --enable-features=ToolbarUseHardwareBitmapDraw
and only works on Android 10 or higher.

This was tested via generating traces with software/hardware
drawing, using the same query used for the previous CL.
