Add ability to specify custom document transform during manifest generation

[jerelmiller]

Apollo Client v3.8 added support for custom document transforms that can be used to modify queries before they are sent to the server. This PR adds support for this feature during manifest generation to ensure the queries saved to the manifest match what will be sent by the client in a running app.

Ping me when the README is ready. Looks like this doesn't solve the particular onboarding use case we thought it might, but it's still a great idea.
