Switch presubmit CI workflows to use pinned IREE versions. (#774)

Progress on #760.

The idea here is that we will test with only pinned versions in all
workflows that run on `pull_request` and `push` triggers, then we will
create pull requests (ideally via automation like dependabot) that
attempt to update the pinned versions. This will give us confidence that
test regressions are _only_ due to the code changes in the pull request
and not due to a dependency changing. Workflows will also be more
reproducible as the versions they fetch will come from source code and
not an external, time-dependent source.
