Use different Ubuntu pools for Ubuntu tests to avoid disk space issues. (#20742)

- Use different Ubuntu pools for Ubuntu tests to avoid disk space issues.
  - Updated the `default-build.yml` to have a new parameter specific to Ubuntu listed `useHostedUbuntu`. If we feel the need to expand the parameters usage outside of the Ubuntu configuration we can always rename to `useHosted`. Also didn't want to touch the `isTestingJob` because I wasn't sure of hte implications.
  - Updated the Ubuntu test job to turn off hosted pools.

Fixes https://github.com/dotnet/aspnetcore-internal/issues/3574

- Hmm, are `queue` names case-sensitive?
- Correct `useHostedUbuntu: false` placement
- Correct placement of `useHostedUbuntu: true` default
- Try adding `--without-http_rewrite_module` to nginx configuration
  - also add `set -euo pipefail` to the script for fast failure
