Implemented basic macro expand functionality (#20579)

* Implemented level based macro expand functionality

- it can handle single macro call or expand whole function/proc/etc and it

- In addition, I have altered the parser to provide the endInfo for the node.
The usefulness of the `endInfo` is not limited to the `expandMacro`
functionality but also it is useful for `ideOutline` functionality and I have
altered the ideOutline functionality to use `endInfo`. Note `endInfo` most of
the time is lost during the AST transformation thus in `nimsuggest.nim` I am
using freshly parsed tree to get the location information.

* Make sure we stop expanding correctly

* Test CI

* Fix tv3_outline.nim

compiler/ast.nim
