refactor: reusable workflows for tileset composers

[casswedson]

Summary

reduce the amount of code needed to set up new tilesets

this also makes it easier to maintain all the workflows, they now share a file where all the logic and commands are stored

Content of the change

now setting up a tileset testing workflow looks like this:

• where we set the most important parts, like the event triggers and path filtering

after that we call a workflow template, similar to a github action with inputs etc. the file has all the code needed to compile a tileset for testing and pushing the result artifact

name: GiantDays composer

on:
  push:
    branches:
      - master
    paths:
      - 'gfx/GiantDays/**'
      - '.github/workflows/giantdays_ci_build.yml'
  pull_request:
    branches:
      - master
    paths:
      - 'gfx/GiantDays/**'
      - '.github/workflows/giantdays_ci_build.yml'

jobs:
  build:
    uses: ./.github/workflows/composer_template.yml
    with:
      tileset: GiantDays
      composer-args: --use-all
