This commit adds support for combining code coverage reports
in the test runner. This allows coverage to be collected for
child processes, and by extension, the test runner CLI.

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.

Re-output failing tests after summary has been printed.
This behavior follows other popular test runners
(e.g. jest, mocha, etc...).
Updated SpecReporter:
1. When there is a 'test:fail' event, the test will be
stored.
2. After no more input, all the failed tests will be
flushed.
3. Extract the logic for formatting a test report
into a re-usable function.

This commit addresses a previously untested branch of the code.
It is possible when using the test runner that an error occurs
outside of a test. In this case, the test runner would simply
rethrow the error. This commit updates the logic to handle the
error in the same fashion as other uncaughtExceptions.

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 is bootstrapped synchronously, with the exception
of importing custom reporters. To better handle asynchronously
throw errors, this commit introduces an internal error type that
can be checked for from the test runner's uncaughtException
handler.
After https://github.com/nodejs/node/pull/46707 and this change
land, the other throw statement in the uncaughtException handler
can be removed. This will allow the test runner to handle errors
thrown from outside of tests (which currently prevents the test
runner from reporting results).

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.
