Multires: Add missing context initialization

Might have caused access to uninitialized memory when foreach()
would have failed for some reason.

Multires: Cleanup, typo in type name

Multires: Store modifier pointer for subdivide

Allows to access its settings during the subdivision process.

Cleanup: `make format` after SortedIncludes change

Code quality: Enable SortedIncludes

Code quality: Enable SortedIncludes in .clang-format

This patch does not include a `make format`, which will follow suit.

Fix T73931: Stereo Viewport Color Management

Stereoscopic viewport didn't support Color Manangement due recent
changes in the color management pipeline. In order to solve the issue we
will migrate the strereo rendering into the GPUViewport. This will share
some textures and reduce required GPU memory.

WindowManager: Remove Stereo Offscreen

Stereo offscreen rendering has been replaced with stereo viewport
rendering. When an offscreen buffer is used it is only used for mono
rendering.

This patch will remove the second offscreen buffer.

Fix (unreported): Crash on accessing active sequence in select groupped operator

This patch moves the NULL check of `actseq` to the correct position, which should happen
before the `channel` is assigned. Otherwise an attempt to call the `sequencer_select_grouped_exec`,
when there is no active sequence and `use_active_channel` set to true, results in a crash.

VSE: Disk cache

This patch implements dumping images from cache to HDD.
The main goal of this system is to provide a means to achieve consistent playback speed mainly for strips that are not possible to preview in real time.

How to use:
Disk cache has own settings in user preferences for path to storage, size limit and compression level.
To use disk cache, you need to check `Use Disk Cache` box, set `Disk Cache Directory`, `Disk Cache Limit` and save or open existing .blend file.
By default sequencer output will be cached only. Manual setting is possible in cache panel.

Uses:
- Replacement or alternative for proxies. Disk cache will work with any strip type, supports float images as well.
- Storage for strip thumbnails.
- Less RAM needs to be allocated for preview cache

How it works:
Disk cache is extension of RAM cache. Every image, that is stored or deleted in RAM will be stored or deleted on HDD as well. Images can be compressed to save space and for use on slower drives. Compressed images are slower to write and read though.
Images are stored in bulk of 100 rendered frames per one file. This is to overcome slow file access time for large amount of files. Drawback is, that if one frame needs to be redrawn, all 100 frames are deleted.
