[CI]Disable early exit to complete all tests (#6482)

### What this PR does / why we need it?
1. Disable the feature to exit early upon encountering an error in order
to complete all tests.
2. Within each partition, tests are re-sorted by `estimated_time` in
ascending order. This allows the CI to cover as many test cases as
possible in the early stages.

### Does this PR introduce _any_ user-facing change?

### How was this patch tested?
