[proposal] Convert test runs into actions

[Fredrik Medley]

I have written a draft about how Bazel can let rule authors depend on test results, for example to aggregate and generate test reports during the build phase. It basically creates a TestResultInfo and exposes ctx.actions.run_test.

The document is available at https://docs.google.com/document/d/1PMRwGzpF1SR7JGHK6OvzlRJeL2Z5oXS6xUpq6ts9Ffc/edit?usp=sharing

This is just an initial draft. I will fill in more details if the proposal sounds reasonable and something the Bazel community is happy to adopt.

Best regards,

Fredrik
