addresses several bugs: 2206097, 2166583, 2261119, 2216759

2206097: Broken suggestions while composing message
2166583: Color artifacts with MDP dithering
2261119: Passion transition animations are rough
2216759: Screen flicker when dropdown list in background window shows or hides

This is part of enabling GPU composition instead of using the MDP. This change
is dependent on another change in the vendor project.

Specifically this change disables the use of EGLImageKHR for s/w buffers
for cache coherency reasons. memcpy is used instead.
