Added Storage Module to homeserver.yaml

WIP of #176

Increase the async timeout value defaults, as larger Matrix servers need more time to complete.

Fixes https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/1749

People often report and ask about these "failures".
More-so previously, when the `docker kill/rm` output was collected,
but it still happens now when people do `systemctl status
matrix-something` and notice that it says "FAILURE".

Suppressing to avoid further time being wasted on saying "this is
expected".

This switches the playbook from devture/rust-synapse-compress-state (a
container image which wraps the upstream-prebuilt amd64 binary of
rust-synapse-compress-state) to registry.gitlab.com/mb-saces/rust-synapse-compress-state
(https://gitlab.com/mb-saces/rust-synapse-compress-state), which builds
rust-synapse-compress-state from source and provides a multi-arch image
that currently works on amd64 and arm64.

Ideally, we'll stop using `:latest` and arm32 support will be made
available upstream as well at some point.
Discussed here: https://gitlab.com/mb-saces/rust-synapse-compress-state/-/issues/1

This makes it easier to use another container image for
rust-synapse-compress-state, which may be storing the binary at another
path.

This is a minor hotfix, needs to be bumped though or new deploys will break (existing deploys not affected by bug).

Changed the commit hash in matrix_synapse_ext_spam_checker_mjolnir_antispam_git_version to latest. Fixes a Synapse ImportError with mjolnir v1.4.1 leading to a Synapse crash-loop.

`roles/matrix-synapse/vars/workers.yml` has not been updated here,
because running `roles/matrix-synapse/files/workers-doc-to-yaml.awk`
seems to cause some trouble with the current `workers.md` file
available at https://github.com/matrix-org/synapse/raw/master/docs/workers.md,
namely lots of:

> FIXME: ADDITIONAL CONDITIONS REQUIRED: to be enabled manually

lines and commented out regex lines.

This is something that remains to be investigated/fixed.

The `to_nice_yaml` helper will by default wrap any string YAML values on
the first space after column 80. This can in worst case yield invalid
YAML syntax. More details in Ansible's documentation here:

https://docs.ansible.com/ansible/latest/user_guide/playbooks_filters.html#formatting-data-yaml-and-json

In short, you need to explicitly provide a custom width argument of a
high number of some kind to avoid the line wrapping.

matrix_synapse_federation_port_enabled can be disabled by users, for
example, when one wants to use the same port for client and federation
requests (docs/configuring-playbook-federation.md).

Fixes https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/1621

For now, we disable the new `com.devture.shared_secret_auth` login type
by default, because it causes problems with Element:
https://github.com/vector-im/element-web/issues/19605

This also becomes the first module to use the new Synapse module system
that got introduced in Synapse v1.46.0.

Despite these upgrades, things should remain functionally identical
as far as bridges, matrix-corporal or other consumers are concerned.

The value of `off` was taken to be a boolean, but it shouldn't be.

Synapse expects a string (currently one of: `all`, `invite`, `off`).

This also removes the `matrix_synapse_version_arm64` variable we've
been dragging around for a long time.

Since https://github.com/matrix-org/synapse/pull/11810, a multiarch Synapse
container image (for AMD64 and ARM64) is released at the same time.

I haven't really traced it (yet), but on some servers, I'm observing
`ansible-playbook ... --tags=start` completing very slowly, waiting
to stop services. I can't reproduce this on all Matrix servers I manage.
I suspect that either the systemd version is to blame or that some
specific service is not responding well to some `docker kill/rm` command.

`ExecStop` seems to work great in all cases and it's what we've been
using for a very long time, so I'm reverting to that.

Synapse v1.51.0 requires to be built with BuildKit since
https://github.com/matrix-org/synapse/pull/11691

The `docker_image` Ansible module does not support BuildKit
(https://github.com/ansible-collections/community.general/issues/514),
so we had to switch to a `docker build` call.

Fixes a issue with room version 1.

Merging has to wait until ARM images are built ofc.

v1.50.0 was found to be buggy for people using a `webclient` listener.
This is fixed in v1.50.1.

We don't use such a listener, so we weren't affected anyway.
