Instrument _check_sigs_and_hash_and_fetch to trace time spent in child concurrent calls (#13588) 
Instrument `_check_sigs_and_hash_and_fetch` to trace time spent in child concurrent calls because I've see `_check_sigs_and_hash_and_fetch` take [10.41s to process 100 events](https://github.com/matrix-org/synapse/issues/13587)

Fix https://github.com/matrix-org/synapse/issues/13587

Implement cancellation support/protection for module callbacks (#12568) 
There's no guarantee that module callbacks will handle cancellation
appropriately. Protect module callbacks with read semantics from
cancellation and avoid swallowing `CancelledError`s that arise.

Other module callbacks, such as the `on_*` callbacks, are presumed to
live on code paths that involve writes and aren't cancellation-friendly.
These module callbacks have been left alone.

Add a spamchecker method to allow or deny 3pid invites (#10894) 
This is in the context of creating new module callbacks that modules in https://github.com/matrix-org/synapse-dinsic can use, in an effort to reconcile the spam checker API in synapse-dinsic with the one in mainline.

Note that a module callback already exists for 3pid invites (https://matrix-org.github.io/synapse/develop/modules/third_party_rules_callbacks.html#check_threepid_can_be_invited) but it doesn't check whether the sender of the invite is allowed to send it.

Add a spamchecker callback to allow or deny room creation based on invites (#10898) 
This is in the context of creating new module callbacks that modules in https://github.com/matrix-org/synapse-dinsic can use, in an effort to reconcile the spam checker API in synapse-dinsic with the one in mainline.

This adds a callback that's fairly similar to user_may_create_room except it also allows processing based on the invites sent at room creation.

Standardise the module interface (#10062) 
This PR adds a common configuration section for all modules (see docs). These modules are then loaded at startup by the homeserver. Modules register their hooks and web resources using the new `register_[...]_callbacks` and `register_web_resource` methods of the module API.

Add missing type hints to handlers and fix a Spam Checker type hint. (#9896)

passed a RoomAlias object.

Pass SSO IdP information to spam checker's registration function (#9626) 
Fixes https://github.com/matrix-org/synapse/issues/9572

When a SSO user logs in for the first time, we create a local Matrix user for them. This goes through the register_user flow, which ends up triggering the spam checker. Spam checker modules don't currently have any way to differentiate between a user trying to sign up initially, versus an SSO user (whom has presumably already been approved elsewhere) trying to log in for the first time.

This PR passes `auth_provider_id` as an argument to the `check_registration_for_spam` function. This argument will contain an ID of an SSO provider (`"saml"`, `"cas"`, etc.) if one was used, else `None`.

Combine SpamCheckerApi with the more generic ModuleApi. (#8464) 
Lots of different module apis is not easy to maintain.

Rather than adding yet another ModuleApi(hs, hs.get_auth_handler()) incantation, first add an hs.get_module_api() method and use it where possible.
