fix(circleci): Switch to using circleci v2 syntax and fix build errors (#4837)

This patch fixes the continually breaking circleci build. The changes made were:
- Switch to using circleci v2 syntax, as the v1 syntax will be deprecated in August.
  It also permits running this build locally using the `circleci` commandline tool.
- Adjust timeouts on error tests to fail consistently on high-performance machines.
- Correct error formatting on error tests.
