This commit updates the logic that checks for the end of the
test run. Prior to this change, it was possible for root.run() to
be called multiple times because of the way pending subtests
were tracked. The extra calls to root.run() were harmless, but
could trigger an EventEmitter leak warning due to 'abort'
listeners being created.

This refactors the code that compiles SourceTextModule for the
built-in ESM loader to use a common routine so that it's easier
to customize cache handling for the ESM loader. In addition
this introduces a common symbol for import.meta and import()
so that we don't need to create additional closures as handlers,
since we can get all the information we need from the V8 callback
already. This should reduce the memory footprint of ESM as well.

The default highWatermark of 16 on the TestsStream class can
have a substantial impact on reporting performance. This commit
sets the TestsStream highWatermark to a very large value and
lets the destination streams (which are more likely to have
meaningful highWatermarks) handle backpressure.

This commit updates the test runner to suppress any output for
filtered tests. Filtered tests no longer generate reporter events,
and the unfiltered tests are renumbered in the output as though
the filtered tests were not present. Skipped tests that are not
filtered are still included in the output.
This change is particularly useful when filtering a large number
of tests, as the previously displayed skip output could be
distracting.

This commit simplifies the logic for tracking test start time.
The start time is now set only when a test/suite begins running.
If the test/suite never runs, a fallback is provided in postRun().

This commit removes a check for the todo flag when determining
if a suite should run. In general, the todo flag should have
no impact on whether or not a test/suite runs. Instead, it should
only impact how the result of the test/suite is handled.

This patch adds `require()` support for synchronous ESM graphs under
the flag `--experimental-require-module`
This is based on the the following design aspect of ESM:
- The resolution can be synchronous (up to the host)
- The evaluation of a synchronous graph (without top-level await) is
also synchronous, and, by the time the module graph is instantiated
(before evaluation starts), this is is already known.
If `--experimental-require-module` is enabled, and the ECMAScript
module being loaded by `require()` meets the following requirements:
- Explicitly marked as an ES module with a `"type": "module"` field in
the closest package.json or a `.mjs` extension.
- Fully synchronous (contains no top-level `await`).
`require()` will load the requested module as an ES Module, and return
the module name space object. In this case it is similar to dynamic
`import()` but is run synchronously and returns the name space object
directly.
```mjs
// point.mjs
export function distance(a, b) {
return (b.x - a.x) ** 2 + (b.y - a.y) ** 2;
}
class Point {
constructor(x, y) { this.x = x; this.y = y; }
}
export default Point;
```
```cjs
const required = require('./point.mjs');
// [Module: null prototype] {
// default: [class Point],
// distance: [Function: distance]
// }
console.log(required);
(async () => {
const imported = await import('./point.mjs');
console.log(imported === required); // true
})();
```
If the module being `require()`'d contains top-level `await`, or the
module graph it `import`s contains top-level `await`,
[`ERR_REQUIRE_ASYNC_MODULE`][] will be thrown. In this case, users
should load the asynchronous module using `import()`.
If `--experimental-print-required-tla` is enabled, instead of throwing
`ERR_REQUIRE_ASYNC_MODULE` before evaluation, Node.js will evaluate the
module, try to locate the top-level awaits, and print their location to
help users fix them.

This commit updates the test harness to prevent top level

This commit removes a redundant call to `reportStarted()`. It is
redundant because a few lines down, `subtest.finalize()` is
called. `finalize()` will find the first test that is ready to
report its data, and then call `report()`, which also calls
`reportStarted()`. This will trigger the `'test:start'` as high
up the test tree as necessary.
