[issue21756] IDLE - ParenMatch fails to find closing paren of multi-line statements

As noted on the PR GH-20753, an incremental change to the current logic doesn't seem like a promising approach.

It seems to me that this will require refactoring the code parsing logic to allow it to incrementally parse lines backwards and forwards in order to find the beginning and end of a code block.
