Improve picture capture debug path
* Fixes hardware bitmap capture
* Fixes mutable bitmap capture (no flickering)
* Adds basic single-frame LRU cache to avoid
repeated readbacks of GPU resources
* Does up-front readback of GPU resources
* Moves serialization off RenderThread again thanks
to up-front readback avoiding needing GPU access
off-thread
* Reduces RAM usage & improves performance by serializing
directly to output stream instead of first copying to
a byte[]
