Update dirty regions when requested to repaint everything

This is a merge from: ag/3827114

The issue was when an HWC implementation was requesting a composer
refresh, it wouldn't actually mark the areas as dirty so the
mustRecompose flag wasn't getting sent when a virtual display was doing
the redraw. That then prevented the changes from its output buffer from
propagating through to the consumer of that surface.

Test: Manually verified refreshes propagate through
