Merge #13
13: dx12 support, finish depth image sample and more.. r=kvark a=msiglreith (The PR is a bit messy, my apologies 😅 ) * Add dx12 backend support, including switching to dylibs over static lib due to linking issues with windows libraries * Finish API sample 06 (depth image) by implementing vkBindImageMemory * Start with sample 07 with adding a simple math lib (copied from an older C++ engine of mine..) * Update `portable` branch to latest version <!-- Reviewable:start --> --- This change is [<img src="https://reviewable.io/review_button.svg" height="34" align="absmiddle" alt="Reviewable"/>](https://reviewable.io/reviews/gfx-rs/portability/13) <!-- Reviewable:end -->
