Submitting multiple command encoders per frame causes hang on Vulkan

Description
Frames hanging for 5-10 seconds (presumably until timeout).
I bisected the issue and found it was introduced in #4967.

Possibly related to #5662

Repro steps
It only happens for me when submitting multiple command encoders with render passes in a single frame.
I don't have a minimal reproduction yet, but I wanted to share in case anyone else has encountered the same issue.

Platform
Ubuntu 22.04, nvidia 4090 - 535.86.10

@PWhiddy can you try on

this specifically addresses Vulkan submission

@Wumpf
That did indeed fix it, thanks!

I posted an earlier issue on this: #5663

That'll be a duplicate now and can be closed.

@ggadwa so, #5681 fixes the issue you reported in #5663?

Yes! Didn't do a lot of testing -- but before it would immediately freeze and with that branch it behaves as it always did.

Delete if too OT, but my game on steam that uses wgpu if you want to include it in your uses wpgu list (released in a couple days, uses the previous wgpu version for obvious reasons): https://store.steampowered.com/app/2933470/Atomite/
