Compositor: Fix image node alpha socket converted into operations twice

When translating image node sockets into operations, unavailable ones (with flag SOCK_UNAVAIL) are converted too. This causes an assertion to fail when selecting a multi-layer image with a "Combined" layer because it's mapping associated "Alpha" socket to operation output twice (as there is an unavailable "Image" socket used for combined too).

During compositing execution there is not need to create unavailable sockets as they are not linked or executed. Assertion fails since commit 93e2491, as now map add_new is used instead of just overwriting last mapped socket.

Revert "Fix: Unavailable sockets are used during compositing execution"

This reverts commit ce7f952e25c238f7bad4da837447c645398a27f3.

Compositor: Fix areas of interest outside operations bounds

They should be cropped instead of clamped.

Compositor: Set current execution model in operations

Operations may share methods between tiled and full frame implementation and they may need to differentiate between them in some cases. This is just a temporal solution while keeping both execution models.

Compositor: Do constant folding for full frame execution

All operations with constant pixel/elements are evaluated into primitive Value/Vector/Color constant operations prior rendering execution. This is the case of operations that are constant only when all their inputs are so. Such operations should set can_be_constant flag to true. is_constant flag is only used for primitive operations (Color/Vector/Value) which are the only constant operations during rendering execution.

Compositor: Crop operations canvases to rendered areas

When calculating operations resolutions (canvas size), rendered areas are not known yet so worst case scenario is assumed which is full size. But they can be cropped to rendered areas bounds one they are known. This reduces memory usage as buffers size will be the same than rendered areas bounds.
