Cycles: add animation denoising Python operator.

This adds a cycles.denoise_animation operator, which denoises an animation
sequence or individual file. Renders must be saved as multilayer EXR files
with denoising data passes.

By default file path and frame range come from the current scene, and EXR
files are denoised in-place. Alternatively, a different input and/or output
file path can be provided.

Denoising settings come from the current view layer. Renders can be denoised
again with different settings, as the original noisy image is preserved along
with other passes and metadata.

There is no user interface yet for this feature, that comes later.

Code by Lukas with modifications by Brecht. This feature was originally
developed for Tangent Animation, thanks for the support!
