Bring auto-accept invite logic into Synapse (#17147)

Browse source 
This PR ports the logic from the
[synapse_auto_accept_invite](https://github.com/matrix-org/synapse-auto-accept-invite)
module into synapse.

I went with the naive approach of injecting the "module" next to where
third party modules are currently loaded. If there is a better/preferred
way to handle this, I'm all ears. It wasn't obvious to me if there was a
better location to add this logic that would cleanly apply to all
incoming invite events.

Relies on https://github.com/element-hq/synapse/pull/17166 to fix linter
errors.

Add the ability to auto-accept invites on the behalf of users. See the [`auto_accept_invites`](https://element-hq.github.io/synapse/latest/usage/configuration/config_documentation.html#auto-accept-invites) config option for details.

## Auto Accept Invites
Configuration settings related to automatically accepting invites.
---
### `auto_accept_invites`
Automatically accepting invites controls whether users are presented with an invite request or if they
are instead automatically joined to a room when receiving an invite. Set the `enabled` sub-option to true to
enable auto-accepting invites. Defaults to false.
This setting has the following sub-options:
* `enabled`: Whether to run the auto-accept invites logic. Defaults to false.
* `only_for_direct_messages`: Whether invites should be automatically accepted for all room types, or only
for direct messages. Defaults to false.
* `only_from_local_users`: Whether to only automatically accept invites from users on this homeserver. Defaults to false.
* `worker_to_run_on`: Which worker to run this module on. This must match the "worker_name".
NOTE: Care should be taken not to enable this setting if the `synapse_auto_accept_invite` module is enabled and installed.
The two modules will compete to perform the same task and may result in undesired behaviour. For example, multiple join
events could be generated from a single invite.
Example configuration:
```yaml
auto_accept_invites:
enabled: true
only_for_direct_messages: true
only_from_local_users: true
worker_to_run_on: "worker_1"
```
