Avoid all sub-package imports from graphql package.

Since we don't control the contents of this package, and nested
subdirectories within the graphql package do not have their own
package.json files with "main" and "module" entry points (like our
`@apollo/client/*` sub-packages do), it is unfortunately not safe to reach
into the package to import specific items, as demonstrated by apollographql#7184.

This could cause a bundle size regression for bundlers that do not perform
any tree-shaking, but it's the responsibility of the graphql package
maintainers to support selective sub-package imports if they want to.
Until that happens, @apollo/client must import from the graphql package in
the only supported way: directly from the top-level package.
