Qute Debugger prototype demo

[maxandersen]

This is mainly an issue to record the ideas around the current debugger prototype for Visual Code and Intellij made by @angelozerr. You can step through templates, see state, evaluate qute expressions, put breakpoint - pretty cool and powerful debugger if you ask me ;)

To work best it needs this qute pr.

I recorded demo where @angelozerr walks through how to use this with qute standalone (start of video) AND from within a quarkus application.

Video is here https://youtu.be/v3qMqjxAhPo and timestamp 8:55 is where Quarkus qute debug is shown

Steps on how to reproduce this in intellij:

1. Clone https://github.com/angelozerr/test-qute-debugger
2. Install LSP4IJ (to have DAP support in intellij)
3. Run https://github.com/angelozerr/test-qute-debugger/blob/master/src/Main.java
4. Set a breakpoint in https://github.com/angelozerr/test-qute-debugger/blob/master/src/main/resources/templates/hello.qute

Let us and particular @angelozerr know if you would be interested in this :)

Thanks @maxandersen to have created this discussion

To work best it needs this #48693.

The PR which provides the capability to track nodes when template is rendering has been merged.

I have created a new draft PR which provides the debugger #48962

@maxandersen please read "Test the debugger (in IntelliJ with LSP4IJ)" section at #48962 which explain how to play with the debugger with IntelliJ and DAP support from LSP4IJ
