Workaround for Github's Ubuntu image getting spurious Asan failures

[Wumpf]

What

Hitting some spurious asan issues on ci: Some Linux runs end up spamming AddressSanitizer:DEADLYSIGNAL indefinitely with no additional information.

Originally I suspected this came from

• Generate fewer .cpp files: Inline forward serialization of transparent components to their respective datatypes #5544

But it's actually a Github image issue, see actions/runner-images#9491

did not work so far https://github.com/rerun-io/rerun/actions/runs/8326523953/job/22782380753?pr=5557

Looks like explicitly disabling worked. Triggering two more manual runs to confirm.

The other changes are a net improvement I think, so keeping them

extra runs:

• ❌ https://github.com/rerun-io/rerun/actions/runs/8327346737

that didn't work out either

disabling ASAN for the changed functions doesn't get us any further it seems.
