[CI] Optimise pipeline deployments with explicit dependencies

[nightah]

Pushes to master and tagged releases will have now have explicit dependencies for steps. This is specifically to prevent darwin based builds holding up execution of other steps which should not have a dependence.

The upstream hardcoded pipeline steps have already been changed to:

steps:
  # Blocking pipeline for master branch deployments (concurrency_group).
  - label: ":pipeline: Setup Pipeline"
    command: ".buildkite/pipeline.sh | buildkite-agent pipeline upload"
    concurrency: 1
    concurrency_group: "deployments"
    if: build.branch == "master"
    
  # Non-blocking pipeline for all others (tagged commits/local branches/PRs).
  - label: ":pipeline: Setup Pipeline"
    command: ".buildkite/pipeline.sh | buildkite-agent pipeline upload"
    if: build.branch != "master"
    
  - wait:
    if: build.pull_request.repository.fork != true && build.branch !~ /^dependabot\/.*/

  # Manual intervention by team required to deploy for forked PRs (prevent secret leakage).
  - block: "Public fork needs approval"
    if: build.pull_request.repository.fork == true
    
  # Blocking deployment for master branch deployments (concurrency_group).
  - label: ":rocket: Setup Deployment"
    command: ".buildkite/deployment.sh | buildkite-agent pipeline upload"
    concurrency: 1
    concurrency_group: "deployments"
    depends_on:
      - "build-docker-linux-amd64"
      - "build-docker-linux-arm32v7"
      - "build-docker-linux-arm64v8"      
    if: build.branch == "master"
  
  # Non-blocking deployment for all others (tagged commits/local branches).
  - label: ":rocket: Setup Deployment"
    command: ".buildkite/deployment.sh | buildkite-agent pipeline upload"
    depends_on:
      - "build-docker-linux-amd64"
      - "build-docker-linux-arm32v7"
      - "build-docker-linux-arm64v8"   
    if: build.branch != "master" && build.branch !~ /^dependabot\/.*/ && build.pull_request.repository.fork != true
    
  # Removed dependency optimisation for forked PRs to enforce block step.  
  - label: ":rocket: Setup Deployment"
    command: ".buildkite/deployment.sh | buildkite-agent pipeline upload"
    if: build.pull_request.repository.fork == true
