feat: Compile array comprehensions to Hugr

[mark-koch]

• Refactor compilation of list comprehensions so we can use the same logic for array comprehensions. The only difference is that lists call push to add the next element to the accumulator whereas arrays use set and update a counter. This is now implemented via a build_update hook provided to _compile_generators
• Store checked Globals inside the compilation context so we can invoke Guppy methods by name while building Hugr
