feat(integ-runner): support --language presets for JavaScript, TypeScript, Python and Go

[mrgrain]

It was already possible to run tests in any language by providing --app and --test-regex directly.
This change introduces the concept of language presets that can be selected.
By default all supported languages will be detected.

Users can run integration tests for multiple languages at the same time, using the default preset configuration.
To further customize anything, only a single language can be selected. However it's always possible to call the integ-runner multiple times:

integ-runner --language typescript
integ-runner --language python --app="python3.2"
integ-runner --language go --test-regex=".*\.integ\.go"

Resolves part of #21169

Unsupported languages du to lack of testing

{     
      // works but it's a bit ugly to need to have a project per test case - is there a better solution?
      csharp: ['dotnet run --project {filePath}', ['^Integ.*\\.csproj$']],
      fsharp: ['dotnet run --project {filePath}', ['^Integ.*\\.fsproj$']],
      // untested, but should be working
      go: ['go mod download && go run {filePath}', ['^integ_.*\\.go$']],
      // this doesn't work. See previous PR attempts for ideas
      java: ['mvn -e -q compile exec:java', ['^Integ.*\\.java$']],
}

Awesome!!

If I'm reading everything correctly you can run it for multiple languages if you
just use the defaults, but if you want to customize anything you can only run it
for a single language? Is that right?

[mrgrain]

Yes that's right. It's because we only have a single pair of --app and --test-regex. A possible future extension would be to allow configuring the presets or support passing in a map of app -> test-regex.

In the meantime, if both is needed, users can always run integ-runner multiple times, e.g.:

integ-runner --language typescript
integ-runner --language python --app="python3.2"
integ-runner --language go --test-regex=".*\.integ\.go"

Very cool!
