Move roles/matrix* to roles/custom/matrix*

Browse Source 
This paves the way for installing other roles into `roles/galaxy` using `ansible-galaxy`,
similar to how it's done in:

- https://github.com/spantaleev/gitea-docker-ansible-deploy
- https://github.com/spantaleev/nextcloud-docker-ansible-deploy

In the near future, we'll be removing a lot of the shared role code from here
and using upstream roles for it. Some of the core `matrix-*` roles have
already been extracted out into other reusable roles:

- https://github.com/devture/com.devture.ansible.role.postgres
- https://github.com/devture/com.devture.ansible.role.systemd_docker_base
- https://github.com/devture/com.devture.ansible.role.timesync
- https://github.com/devture/com.devture.ansible.role.vars_preserver
- https://github.com/devture/com.devture.ansible.role.playbook_runtime_messages
- https://github.com/devture/com.devture.ansible.role.playbook_help

We just need to migrate to those.

Trying to append postgres-exporter's reverse-proxying configuration to matrix-nginx-proxy,
but it's pointless since the matrix-nginx-proxy role had already executed.
To fix this, please change the order of roles in your playbook,
so that the matrix-nginx-proxy role would run after the matrix-prometheus-postgres-exporter role.
