Extending lsp.client with support for DAP

[jtulach]

I'd like NetBeans to have a support for DAP. To debug GraalVM based languages as well as Python, for example.

Debugging Python inside NetBeans

Run the Python file like this:

$ python -m debugpy --listen localhost:5678 --wait-for-client <file>.py

It should now wait for connections from the IDE. In the IDE, select Debug/Attach Debugger...:

In the dialog, fill in:

• Debugger: Debugger Adapter Protocol (DAP) Debugger
• Hostname: localhost
• Port: 5678
• Connection type: Attach
• Additional configuration:

{
    "arguments": {}
}

• Attach after configure - unchecked

Confirm the dialog - the IDE should now debug the Python code.

The debugging works with GraalVM based languages as well. Just download GraalVM for JDK 17 and Graal.js 17 and debug sieve.js with following command sieve/js$ /graalvm-17/bin/js --dap sieve.js:

debugger connects and one can step over the code.
