perf: remove unused ASTNode parsing

[antazoey]

What I did

fixes: #ApeWorX/ape#1726

How I did it

• Del ASTNode logic for now as there are no tracing features yet in solidity so this does not affect anything and it was too pre-emptive to add anyway. I would like to get tracing features working and somehing like this is a first step, but the performance concerns leads me to think are going to probably want the raw dicts in the manifest instead and parse them later so compiling alone does not take forever, but will probably adjust ape-vyper like that first.

How to verify it

I couldn't get the regression testing portion figured out... It is stupidly complicated I guess and I can't really find a decent example.

For now will have to rely on looking at the output from past CI runs...
