feat: Replace pip-compile with uv (#4460)

* Update `shell.nix`

- Replace pip-compile with uv packages
- Pin rust version
- Add var to trigger windmill print more info in stdout

* Replace `pip-compile` with `uv` (dirty + untested)

* Fix arguments passed to uv

Some of the flags are included by default in UV and can be safely removed:
- --resolver=backtracking
- --no-emit-index-url

Also uv does not support `--pip-args` and suggests to directly pass args to uv.

* Remove extra `dbg!`

* Replace 'pip-compile' with 'uv' in Dockerfile

* Add fallback option to `pip-compile` (Disabled)

* Add `uv` to `docker/DockerfileSlim*`

* Add `get_annotation_python` and rename `get_annotation` to `get_annotation_ts`

* Add option to fallback to pip-compile

Put `# no_uv` on top the file for specific python script

Or set `USE_PIP_COMPILE` variable to `true`

* Put back `pip-tools` into shell.nix

* Make sure lockfile resolves again if `#no_uv` used

Add #no_uv to the end of requirements (requirements.in)
That way if something breaks for customer, then they put #no_uv and new lockfile will be resolved

* Put `pip install pip-tools` in original spot

* Fix compilation error

* Fix EE compilation error

    = note: see issue #15701 <https://github.com/rust-lang/rust/issues/15701> for more information

* Add `no_cache` annotation

Will force recalculation of lockfile
And block uv from using cached values

* Target uv cache to /tmp/windmill/cache

* Prohibit uv from managing python

* Add uv to DockerfileBackendTests

* Pin uv version to 0.4.18 in Dockerfiles

* Dont put `#no_uv` in requirements.in

Instead postfix hash for requirements.in with `-no_uv`

* Push Warning to logs if fallbacked to pip-compile
