Introduce new `TestsStream` events `test:stderr` and `test:stdout`
to delegate `stderr` and `stdout` (e.g. `console.log()`) formatting
to the reporter. And patch existing reporters to:
- Spec: output the message as it is
- TAP: stay the same with existing `test:diagnostic`

This commit adds code coverage functionality to the node:test
module. When node:test is used in conjunction with the new
--test-coverage CLI flag, a coverage report is created when
the test runner finishes. The coverage summary is forwarded to
any test runner reporters so that the display can be customized
as desired. This new functionality is compatible with the
existing NODE_V8_COVERAGE environment variable as well.
There are still several limitations, which will be addressed in
subsequent pull requests:
- Coverage is only reported for a single process. It is possible
to merge coverage reports together. Once this is done, the
--test flag will be supported as well.
- Source maps are not currently supported.
- Excluding specific files or directories from the coverage
report is not currently supported. Node core modules and
node_modules/ are excluded though.
