Metal: deferred render command encoder creation.
MTLRenderCommandEncoder creation will be deferred until a render pass
ends.
Commands will be stored into a back-end owned buffer during render pass.
At the end of the render pass, those commands will be re-encoded into an
actual MTLRenderCommandEncoder.
Benefits:
- Useful for future implementation of occlusion query buffer where it
could be allocated right before the end of a render pass to be big
enough to store all queries within the render pass.
- It's possible to change load option (deferred clear) as long as there
is no draw call issued yet. This is not implemented yet.
- Possibility of commands' re-ordering.

Metal: Fix FramebufferMtl's read-after-delete
Due to late verification, ContextMtl might call onFinishedDrawingToFrameBuffer()
on a deleted framebuffer object inside syncState()
Fix:
- Switch to call onStartedDrawingToFrameBuffer() on new FBO instead of
calling onFinishedDrawingToFrameBuffer() on old (and possibly deleted)
FBO.
- Also discard framebuffer only takes effect per render pass. The
discard flag will be reset when render pass starts.
