ci: remove merge-queue and consolidate CUDA base tests (#2074)

The merge queue is unstable and blocking PR merges due to not all jobs
completing from workflow API flakiness or runner flakiness.

We will go back to merging to main and running workflows on push to main
for now.

Additionally, I consolidated the primitives, vm, recursion CUDA tests to
one runner to save some runners (and possibly compile time).
