fix(ext/node): New async setInterval function to improve the nodejs compatibility

[cu8code]

#26499

This PR adds a better implementation of setInterval using async functions, similar to the one in Node.js. It's mostly based on the Node.js version, with some updates to error handling and logic.

The PR is complete, but I need help with:

• Running a single test file
• Deciding where to place my test files

Currently, I have a test to validate my code, but I’m running it outside of cargo test because running all tests at once is frustrating and often causes my system to freeze due to high memory use. This issue occurred even before my changes.

Thanks for the PR!

Deciding where to place my test files

I would recommend adding your test as a unit test to this file:

deno/tests/unit_node/timers_test.ts

Lines 102 to 110 in 770ef14

	Deno.test("[node/timers setImmediate returns Immediate object]", () => {
	const { clearImmediate, setImmediate } = timers;
	const imm = setImmediate(() => {});
	imm.unref();
	imm.ref();
	imm.hasRef();
	clearImmediate(imm);
	});

Running a single test file

Assuming you've added your test to tests/unit_node/timers_test.ts, you can run that file one of two ways:

• With cargo

   cargo test node_unit_tests::timers_test

  this will execute all of the unit tests in timers_test.ts
• You can also build deno with cargo build and then run the tests using the binary, so

  cargo build
  ./target/debug/deno test -A --config tests/config/deno.json tests/unit_node/timers_test.ts

  that will run the tests with a normal deno test, so you can filter specific tests within that file like you normally would

@nathanwhit I've moved the test to the appropriate directory, so the PR should be ready for merging. Please take a look when you can. Also, thanks for the tip about running directly from the target directory—it made things a lot easier!
