Alex Chau cb2b925a50 Reland "Reduce calls to surface reparenting and set relative layer"

Surface reparenting was happening on every frame since we call
applyDepthAndBlur on each frame during animation. Instead we can do it
only when base surface is set. mBlurSurface should always be parented to
mBaseSurface so no point in calling it again and again.

Relative layer changes only when we either draw above or recents. While
drawing above recents, mBaseSurface relative layer should be used.
mBaseSurfaceOverride otherwise. No point to call this during animation.

Added perfetto traces comparison home->all apps, alongwith all other
generic overview scenarios which possibly could have caused jank is
added here:
