[Breaking change]: Return everything that is created during an api interface function & add a context object to all functions

[rishabhpoddar]

For example:

• the sign up / sign in api interfaces create a new session and a new user. Both should be returned.
• third party sign up / in also fetch the auth code response so we should return that as well (which we already do).

This is as per a new design principle that we have added.

---

We should also add a context object to all functions (API, recipe and sending email functions) which can be freely modifed by the user to pass info across the functions.

These should also be added to the user facing function signatures, but should be optional there.

The should also be added to functions like createAndSendCustomEmail etc..
