What is the problem this feature will solve?

#39085 added process.setSourceMapsEnabled to enable source-maps programmatically. This is helpful for tools like Vite, thank you for implementing. 💚

But as this was implemented we now cannot know whether source-maps are enabled. I guess it was possible by process.execArgv.includes('--enable-source-maps') previously.

What is the feature you are proposing to solve the problem?

Add process.getSourceMapsEnabled that returns whether the source-maps are enabled.

What alternatives have you considered?

Add a getter + setter named process.isSourceMapsEnabled that works like process.getSourceMapsEnabled and process.setSourceMapsEnabled.
