Split componentize and transpile

[blaine-arcjet]

A lot of work is currently going into the "componentize" logic of jco; however, this means it is taking on a ton of dependencies.

If users, such as arcjet, only want to transpile, they should not have to take on this supply chain risk.

We're in the process of discussing where ComponentizeJS best belongs, and currently it's an open question and has been considered on both sides for either moving ComponentizeJS into Jco or moving ComponentizeJS into StarlingMonkey.

This is a good datapoint to hear on the side of moving it into StarlingMonkey and I'll be sure to bring this argument up.
