Fix circular dependency with DocumentTransform import in InMemoryCache

[jerelmiller]

Issue Description

When testing out the first beta release, I tried to run @apollo/client in a CLI environment and it blows up trying to instantiate InMemoryCache. When logging the import, it appears everything from the cache module is set as undefined. Through trial and error, I have narrowed it down to #10509 which introduced the new custom document transform feature.

Re-reviewing that PR, I noted that InMemoryCache imports the DocumentTransform from core, yet core exports modules from cache resulting in a circular dependency. While some bundlers seem to be able to resolve circular dependencies, running this in the CLI environment fails entirely.

Since DocumentTransform is used both by core and by the cache, we should move that module to a neutral location to avoid the circular dependency.

Reproduction Steps

Use the new generate-persisted-query-manifest tool and notice that it blows up with the error:

TypeError: core_1.InMemoryCache is not a constructor
    at generatePersistedQueryManifest (/node_modules/@apollo/generate-persisted-query-manifest/dist/index.js:66:16)
