Run tests in the same process for debug/inspect

Add a flag like runInBand

@sirenkovladd, can you help me on this idea?

With isolated processes, I have the advantage of allowing .ts, .cjs, .mjs, etc. to run in the exactly same suite.

By removing the isolation (running the tests in the same process), it comes with some intentional limitations:

• Different structures (.ts vs. .js, CommonJS vs. ES Modules) must be executed in an exclusive suite.

In this case, the possibility of disabling isolation would be in line with your idea.

I think this is expected
I think everyone who uses debug tries to execute the least number of tests (close to 1 test)
