Previously it was only working for the single layer case. For multipart
we write the colorspace in each part. For single part we write the first
non-data colorspace, and hope data passes will be identified based on channel
name like Blender does (e.g. XYZ instead of RGB).
Reading is unchanged and still the same as before, in that it only reads the
colorspace from the first part. There is only one color space per image
datablock, so we can not store anything more currently. In practice it
would be unusual for all passes in a file not to either have the same
colorspace or be data.
All the compositor file output test images were updated to include the
metadata, so that the test will check if the metadata is there.

New "Interleave" option in image format settings, enabled by default in old
files and disabled by default in new files to write multi-part files.
By not storing all channels interleaved, it is possible for other applications
to load individual passes more efficiently. This might also work better with
compression.
We follow the OpenEXR docs in that the channel name is the full
Layer.Pass.Channel rather than just Channel. Some other renderers
(e.g. Houdini Karma) write just the channel and that is what our reading
code assumed so far.
I've verified that Nuke can read the multipart EXR files produced by Blender,
including multiview and cryptomatte.

This patch redesigns the File Output node to provide better UX and UI.
This is mainly achieved by allowing the user to create inputs by
dragging into an Extend socket and adjust existing inputs using the
familiar UI list design available in Blender. Additionally, various UI
changes were done:
- The Use Node Format option was renamed to Override Node Format for
clarity.
- Socket types are now fixed and do not change as new links are made,
allowing users to specify the exact output type and employ implicit
conversion if needed.
- The distinction between images and Multi-Layer EXR was made clearer.
- Final output paths are drawn in the UI to remove guess work.
- The Base Path was split into a Directory and a File Name.
- Panels were added to group options, include a panel for the node
format, items, and item formats.

'exr multilayer passes' had an invalid input, so its output was updated
The rest of the tests had outdated output sockets after some 'Color'
sockets were converted into 'Vector' sockets

This change moves the tests data files and publish folder of assets
repository to the main blender.git repository as LFS files.
The goal of this change is to eliminate toil of modifying tests,
cherry-picking changes to LFS branches, adding tests as part of a
PR which brings new features or fixes.
More detailed explanation and conversation can be found in the
design task.
