WIP: [parser] Fix arrow function name inferring

This is a reland of part of
https://chromium-review.googlesource.com/c/v8/v8/+/1397664.

It drops the explicit fni_.Infer() call after parsing arrow functions. We'll
want to avoid inferring if the arrow function is an argument to a function
call.

It also avoids adding the single argument of "name => " to the inferred name.
