Qute support for multi module project

[angelozerr]

When project contains multi-module with some projects which are Qute project, it doesn't work, because today we consider that a workspace folder is a project which is wrong, because a workspace folder could contains several maven module which could be a Qute project.

To fix that we need to:

• not use workspace folder to load Qute project
• having on JDT / IJ side a new services:
  • java/qute/projects request -> return all Qute projects from rootUri
  • java/qute/projectAdded / java/qute/projectRemoved notifications to notify the language server that a new Qute project has been added/removed from the workspace.

Here a sample multi-qute.zip which fails on vscode, IJ, Eclipse IDE

The sample https://github.com/redhat-developer/intellij-quarkus/issues/1164#issuecomment-1722277133 show that we need to load qute project with dependencies
