Merge shared functionality from render and compute passes

[Vecvec]

Connections
Preparation for ray tracing pipelines (specifically the new pass that would be added).

Description
There were many duplicated functions, and some duplicated functionality between render and compute passes when actually recording the commands. This confused me, and I didn't realise there were two set_bind_group functions, and so some ray tracing validation was only in one. To implement ray tracing pipelines, a third pass would have to be introduced, which would cause a third duplication of this code.

Some things to note:

• For some reason, compute passes used a tracker which took things from a usage scope, while render passes just used the usage scope directly. I couldn't find a reason this was necessary, but there might be a particular reason. re-added this.
• Compute passes have an extra push constant field to reset push constants after indirect validation, there was a todo there, but I couldn't see why, and removed it as part of the refactor, but I can add it back if needed.

Testing
Tries to just keep all existing functionality.

I am sorry about the conflicts from #7820. Some of the changes are just whitespace changes, it would probably help to look at that diff with whitespace changes ignored to get a sense of what's really going on. Let me know if I can help somehow.

I wonder if making things generic over errors like I did with validate_pass_timestamp_writes could help to avoid the extra GeneralPass layer in the errors?

I hadn't thought of that, I'll give it a try.

Looks great overall - thanks for unifying these!

Added unit structs for those errors. Definitely make stuff clearer.

Nice!
