Vulkan as renderer

- [x] I have checked that a similar [feature request](https://github.com/Genymobile/scrcpy/issues?q=is%3Aopen+is%3Aissue+label%3A%22feature+request%22) does not already exist.

**Is your feature request related to a problem? Please describe.**
No.

**Describe the solution you'd like**
Using Vulkan as graphical renderer, benefiting its high performance and low cpu usage.

**Describe alternatives you've considered**

**Additional context**

The issue names no files, tests, or entry points. Start by locating the existing graphical renderer and its rendering backend, then determine the project’s Vulkan integration requirements; done would mean a working Vulkan renderer with appropriate validation and performance coverage.
