related issue = #3178
This PR fixes 3 things:

  1. During ti.sync(), submit the cmd list if it hasn't been submitted.
  2. Write the cell size back to SNode during struct compilation
  3. Fix a type error in float_atomic. This fixes test_reduction.

Looks good, but I'm a bit confused on the test reduction situation. I have spotted some type errors on the uint side but my fix can't seem to fix the problem @k-ye observed. He said the tests fail on u32 types. (I can't repro any one of the case so I'm chasing it blind)

Huh, Interesting. I observed failures for f32 only.
It's also confusing that CI passed for #3164 as well. How did we discover the test_reduction failure in the first place?

Does VK backend actually use this? That said, we should make this part backend-neutral.

I'm using cell size bytes for computing SNode Device ptr in ggui.
