Improve VSCode configuration

- Update outdated and add new recommended extensions
- Exclude some vendored code from search results by default
- Add more VSCode editor settings that are consistent with our linting
- Provide configuration for coverage visualization in VSCode but disable
  it by default
- Add SimpleCov coverage for `eval` and ensure that we always default to
  line coverage in case upstream defaults ever change
