feat: add fast variant of CI build and smoke test

[john00003]

Motivation

We want a faster version of the dist-build and smoke-test Makefile targets.

Technical Details

The dist-build-fast target improves the build time by:

1. compiling NIXL/UCX with optimizations and other debug tools disabled
2. compiling only for gfx950 (the machines our CI targets)

Additionally, we disable building the tests/examples for both hipFile and NIXL to reduce the build time.

Currently the smoke-test-fast Makefile target doesn't run any different tests than the normal variant, it just uses the docker container built by the dist-build-fast variant.

Test Plan

Try the dist-build-fast and smoke-test-fast, ensure the build and tests pass. Measure the amount of time the reduced Makefile targets take compared to the regular targets.

Test Result

The reduced compile targets and disabling the tests and examples save ~30s. The reduced gfx compile targets save a couple minutes.

We'll need to update the workflows in /usr/ on the CI runners in order for the CI changes to reflect.

✅ Hardware CI passed for dafc0cd (dist-build + smoke-test + tiny-test).
