✨[Feature] Parallelize Dynamo Converter, Backend, E2E Tests in CI #2139
Description
Context
Dynamo tests collectively take over an hour on PR #2070 due to the addition of many new converters. These tests can be parallelized in much the same way FX tests are, currently.
Proposal
Add parallelization to the Dynamo testing pipeline, similar to that which exists for FX. Begin with 4 parallel instances and split the tests from converters, backend, and e2e across those instances to speed up CI testing times.
