Fuzz more realistically with keyword const eval (#15036)
# Description
The parsing logic for several of our keywords is conditional on the
particular commands for those keywords being in scope:


942030199d/crates/nu-parser/src/parse_keywords.rs (L272-L279)

Thus the following involved parsing logic was not fuzzed by the existing
`parse` fuzz target so far.

This adds an additional fuzz target `parse_with_keywords` that loads the
commands from `nu-cmd-lang`. Those are primarily the keyword
implementations, thus the relevant code paths in the parser that depend
on those `DeclId`s and the potential const eval of `if` etc. get
unlocked.

The existing `parse` target is preserved if you have concerns about the
fuzzing breaking containment in some form due to those commands.
