This cache was never written to, only "copied" between sockets in one
case, it dates back at least a decade. It doesn't make sense to store
caches on node trees directly anyway, since they can be used in
multiple places.
If compositing uses renderlayers, and a camera was missing in the
associated scenes, the error message also referred to the scene the comp
tree was in (not the scene of the renderlayer -- which can potentionally
be different).
This was confusing and is now rectified.

Render stored a shallow copy of the scene view layers and views for thread
safety, without proper functions to free it. But with the CoW depsgraph this
scene is already a copy of the original and an additional copy is not needed.
Refactor to use the scene view layers and some other settings directly instead
of making a copy.
This is the conventional way of dealing with unused arguments in C++,
since it works on all compilers.
Regex find and replace: `UNUSED\((\w+)\)` -> `/*$1*/`
This is required by the Metal backend to perform flushing of temporary objective-C resources. This is implemented as a global autoreleasepool, and is to ensure consistency such that all rendering operations, whether called via events, or via main loop will be within an autoreleasepool.

MTLContext provides functionality for command encoding, binding management and graphics device management. MTLImmediate provides simple draw enablement with dynamically encoded data. These draws utilise temporary scratch buffer memory to provide minimal bandwidth overhead during workload submission.
This patch also contains empty placeholders for MTLBatch and MTLDrawList to enable testing of first pixels on-screen without failure.
The Metal API also requires access to the GHOST_Context to ensure the same pre-initialized Metal GPU device is used by the viewport. Given the explicit nature of Metal, explicit control is also needed over presentation, to ensure correct work scheduling and rendering pipeline state.

Related to {D15885} that requires scene parameter
to be added in many places. To speed up the review process
the adding of the scene parameter was added in a separate
patch.
