This moves the methods that create simple resolvers into their own
helper so they can be imported separately, reducing the size of
graphql_helpers.

And update context description to match Rubocop rules.

Most of these are trivial (adding `#to_a` for example, or changing
to use client side argument names). The labels_resolver_spec changes
are more invasive since this spec tested a number of impossible states
(passing arguments not declared by the resolver) - these particular
changes were approved by @acroitor as part of
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/40088.

The authorization_spec changes are made in such as way as to minimise
the impact of changes from
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/40088
from which this work was extracted.

This ensures that these methods work correctly in more cicumstances.

If given a real context, it will be hashified before consumption (not
doing so causes `Context#to_h` to raise a runtime error).

We check for the field on the `object_type` rather than always on the
`described_class` - this makes `resolve_field` usable outside type
specs.

Mutations wrap their arguments in an `input:` type, so this needs
wrapping and unwrapping in the right places.

Also allows tests to create fresh object-types easily.

This makes resolve_field and resolve more complex so that they do not
simulate the execution of a field, but run it precisely as it is run in
the framework.

Doing this makes refactoring much safer, as we can have assurance that
our tests are in line with the real execution environment.
