Extract sorbet_syntax_check!

[amomchilov]

Motivation

There's a small bug in Prism+Sorbet that requires me to pick between --stop-after=parser and --stop-after=desugar (PR for fix). It's easy enough to workaround, but needs access to some Sorbet config, which is nicer to keep contained within this SorbetHelper.

You can see the usage up-stack in #2567

Along the way, I also discovered the --e-rbi Sorbet flag, which is more fitting for this usage. In principle, it would allow us to have multiple overloads in the RBI, though that isn't something that's used by any DSL compilers today.

Implementation
