canvas: Move to shared memory for images and canvas backing stores.

Browse source 
The idea here is to land this before making images and canvas IPC-safe,
because this will shake out bugs relating to the shared memory. There
are currently test timeouts that are preventing multiprocess images and
canvas from landing, and I believe those are due to the inefficiency of
sending large amounts of data in the unoptimized builds we test with. By
moving to shared memory, this should drastically reduce the number of
copies and `serde` serialization.

Under the hood, this uses Mach OOL messages on Mac and temporary
memory-mapped files on Linux.
