Only run the common local engine configurations in presubmit - #195688

Code Review
This pull request refactors the CI build configurations by moving several unoptimized debug build configurations from local_engine.json into a new file, local_engine_common.json. Additionally, a new Linux local_engine_builds_common target is introduced in .ci.yaml, and the engine tool documentation is updated to reference the new configuration file. There are no review comments, and I have no feedback to provide.

nit: it would be ncie to define what local_engine_builds_common means somewhere in english. I'm not sure where the best place to do that would be though.
I added a comment to .ci.yaml and to the et readme that was already referencing it. |

Super nit: With this "presubmit: false" and the other "bringup: true" we lose testing till you land the "remove bringup true" PR. You could swap the order and make local_engine_builds be the common one (with config_name local_engine_commond) and the other could be. local_engine_builds_uncommon.

I actually had this at first, but it made the original json diff itself harder to review.
I hearby promise to remove the bringup true when it passes in CI.
…#195688) `local_engine_builds` compiles all 38 local_engine.json configurations on every engine PR. Move the six debug unopt configurations people actually iterate with to `local_engine_common.json` and make `local_engine_builds` postsubmit-only. Unfortunately `linux/wasm_debug_unopt` is the longest build which is staying in presubmit, so it doesn't reduce the overall wall time of the builder since they run in parrallel.
