Improve CI time using uv for dependency setup (#2041)

SUMMARY:
The goal of this pr is to speed up time to signal on new prs. 

Currently, we have the following CI tests:
- `base-tests`: total runtime `4m26s`, install deps `3m43s`, run test
`30s`
- `pytorch-tests`: total runtime `3m27s`, install deps `3m4s`, run test
`12s`
- `quality-check`: total runtime `3m3s`, install deps `2m58s`, run test
`0s`

*times based on runs from this pr
#2040. Note exact
times will fluctuate substantially.

After this pr, we have:
- `base-tests`: total runtime `1m14s`, install deps `16s`, run test
`41s`
- `pytorch-tests`: total runtime `55s`, install deps `14s`, run test
`22s`
- `quality-check`: total runtime `19s`, install deps `10s`, run test
`0s`

*times based on runs from this pr
