[PLAY-648] Multi platform images

[koncar]

Idea is to build multiplatform image, but since cross platform building ARM64 image is really slow (20mins) we will also build old way.

jobs:

• build-single-platform - it's old way of building images (no qemu/buildx)
  this job runs on PR requests, dev* branch, and also master branch
  it is fast, and it will be first to built and pushed to docker hub, so that image that works for most situations is available quickly.

• trivy security scans, wait for build-single-platform to complete, and run security scan based on that. It also triggers on schedule, and uses that image

• build-multiplatform - this is new really slow way of building image
  this job runs only on master
  it is slow, and it will overwrite build-single-platform image once it completes. It should work for all distributions
  merge waits for build-multiplatform job and it combines all platforms into single tag

pipeline:

single platform image (old) - pushed first

multi platform image(new) - which overwrites single platform image when it's built from main branch
