Some ET workflows running on PRs are not cancelled when the PRs are updated

[huydhn]

For example,

executorch/.github/workflows/cuda.yml

Line 35 in 7c4cae6

cancel-in-progress: false

executorch/.github/workflows/cuda-windows.yml

Line 24 in 7c4cae6

cancel-in-progress: false

executorch/.github/workflows/rocm.yml

Line 39 in 7c4cae6

cancel-in-progress: false

These workflows all have cancel-in-progress: false. We need to verify if that option is needed.
