graphics: rework IComposer 

Similar to IAllocator, introduce IComposerClient to manage resources.
Rework the interface such that most state changing calls are batched in a
"command buffer" and execute together.  The goal is to reduce the number
of IPC calls needed to set up the composer.

Test: builds and boots
