Reland "Simple frame production"

This is a reland of commit 23a50951556c98fab168260ac37c32006fe546d1

Update OnBeginFrame call in tests to match new signature.
No other changes.

Original change's description:
> Simple frame production
>
> A simple frame production algorithm. Supports:
> * a single root render pass only
> * Layer position, transform
> * SetMaskToBounds for axis-aligned layer
>
> Add AppendQuads for SolidColorLayer as the simplest layer for unit
> testing.
>
> Notable missing features:
> * Non-axis aligned clip and filters (requires non-root pass)
> * Damage tracking
> * Quad occlusion culling
> * Visible rect on quads
>
> Add test harness to unit test frame generation.
