Use conan to get Vulkan

[IceflowRE]

Added: Conan dependency caching based on conanfile.py SHA. Whenever we change that file we have to compile the dependencies completly new. We could still load the old cache in those cases, but we currently have no elegant way to delete the old files. My experiment with a Python script were problematic here and there, not very easy to maintain.

Build Times:

• With cache:
  • Ubuntu: ~2min
  • Windows: ~3min
• Without cache:
  • Ubuntu: ~11-15min
  • Windows: ~10-13min
• Downloading SDK:
  • Ubuntu: ~2-3min
  • Windows: ~4min

With cache building we gain around 1min and also reduce the bandwidth consumption with servers outside of GitHub. Also we have a better control over which vulkan headers and tools are used to build, also making reproduceable builds more likely. The only downside is clang-tidy being 1min slower due to bigger cache. Also clang-tidy itself takes 2 min longer??
