Drop support for delegating email validation (#13192)

* Drop support for delegating email validation

Delegating email validation to an IS is insecure (since it allows the owner of
the IS to do a password reset on your HS), and has long been deprecated. It
will now cause a config error at startup.

* Update unit test which checks for email verification

Give it an `email` config instead of a threepid delegate

* Remove unused method `requestEmailToken`

* Simplify config handling for email verification

Rather than an enum and a boolean, all we need here is a single bool, which
says whether we are or are not doing email verification.

* update docs

* changelog

* upgrade.md: fix typo

* update version number

this will be in 1.64, not 1.63

* update version number

this one too

Synapse vNext
=============
As of this release, Synapse no longer allows the tasks of verifying email address ownership, and password reset confirmation, to be delegated to an identity server. For more information, see the [upgrade notes](https://github.com/matrix-org/synapse/blob/release-v1.63/docs/upgrade.md#upgrading-to-v1630).

# Upgrading to v1.64.0
## Delegation of email validation no longer supported
As of this version, Synapse no longer allows the tasks of verifying email address
ownership, and password reset confirmation, to be delegated to an identity server.
To continue to allow users to add email addresses to their homeserver accounts,
and perform password resets, make sure that Synapse is configured with a
working email server in the `email` configuration section (including, at a
minimum, a `notif_from` setting.)
Specifying an `email` setting under `account_threepid_delegates` will now cause
an error at startup.
