2403: Feature: switch CI/CD from build to buildx r=mergify[bot] a=Diman0

## What type of PR?

Feature and enhancement

## What does this PR do?

Switch from docker build to buildx for CI/CD.
    - The main workflow file has been optimised and simplified.
    - Images are built in parallel when building locally resulting in much faster build times.
    - The github action workflow is about 50% faster.
    - Arm images are built as well. These images are not tested due to restrictions of github actions (no arm runners). The tags of the images have -arm appended to it. The arm images are built on merge on master and release branch (x.y). They do not influence the normal CI/CD workflow used for bors (for PR) and real releases (merge on master and branch x.y for x86_64). 
    - Arm images (and normal x86_64 images) can also be built locally.
    - Reusable workflow is introduced for building, testing and deploying the images. This allows the workflow to be reused for other purposes in the future.
    - Workflow can be manually triggered. This allows forked Mailu projects to also use the workflow for building images.

The main workflow makes use of github actions cache to store the cache layer. This layer is used to quickly rebuilt the images in the testing step and deploy step.

Unfortunately the building the arm images fails sometimes due to timeouts. Sometimes the connection to github actions cache is very slow. Restarting the workflow from the last failed step resolves this. I have not observed this with the normal build.

Just as previous time, you can use a forked project for testing the changes (https://github.com/Diman0/Mailu_Fork). You should still have owner access. I have created branch 1.11 for testing. You can see I already push 4 times to branch 1.11 (current version is 1.11.3).
