1.0.2 is the first container image tag that is available as a multi-arch image
with support for linux/amd64, linux/arm64/v8 (arm64) and linux/arm/v7 (arm32),
so self-building is no longer necessary on all these platforms.

it's required if enabled by the dimension config here:

Doing this further simplifies examples/vars.yml.

We're trying to move away from implementation-specific variables,
hoping for a clean (implementation-neutral) examples/vars.yml file.

Doing this seems more reasonable and simpler.

The goal is to have a single variable which tells us which homeserver
software is in use. Much simpler than having if/elif/elif checks for
variables like (`matrix_synapse_enabled` and `matrix_dendrite_enabled`, etc.)
everywhere.

This brings dendrite.yaml up to date and cleans things up a bit.

* Copy/update mautrix_facebook group_vars to mautrix_twitter
* Replace facebook -> twitter, fb -> twt, remove presence var
* Enable playbook in setup.yml

This is useful when Synapse is using a worker setup. In that case,
we don't want appservices to connect to `matrix-synapse:8008`, because
not all APIs are exposed there.

Add a self-build option for the Dimension Dockerfile.
 - This helps further support arm64 hosts (i.e. A1.Flex w/Oracle)

This change forces ansible to decrypt the variable with ansible-vault if encrypted, to avoid the error '{"msg": "Unexpected templating type error occurred on ({{ matrix_synapse_macaroon_secret_key | password_hash('sha512') }}): secret must be unicode or bytes, not ansible.parsing.yaml.objects.AnsibleVaultEncryptedUnicode"}'
Every other variable in the playbook was found to have no problems with encryption.
The change has no negative impact on non-encrypted matrix_synapse_macaroon_secret_key.
