This commit moves code coverage collection from the test
harness exit handler to the postRun() function of the root
test.
This is necessary preparatory work for supporting
code coverage with --test. The reason is that --test is
implemented on top of run(), and that function calls the root
test's postRun() function, which outputs the test summary. This
happens before the harness exit handler.

This commit replaces the 'coverage' reference inside of the Test
class with a more generic harness reference which includes
coverage. This will let the root test more easily track process
level state such as code coverage, uncaughtException handlers,
and the state of bootstrapping.

The test runner relies on a few CLI options. That code was spread
across a few locations. This commit centralizes that logic.

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.
