✨ Add issue tree view

[rszwajko]

Layout:

1. group incidents by message (top level) and file (2nd level)
2. within message group the files are sorted based on the entire path
3. within file group the incidents are sorted based on line number

Actions:

1. top bar
   1. open Analysis webview
   2. expand all nodes
2. context:
   1. open details in Analysis webview (currently just opens the webview)
   2. expand all child nodes
3. one-click expand for nodes with only one child
4. open Analysis webview when extension is loaded (first time the perspective is accessed)

Refactorings:

1. move Analysis web view to the editor section (similar to Resolution webview)
2. disable full screen toggling for Analysis webview
3. embed initial state data in the HTML to ensure that first message won't be missed
