Introduce graphics/egl-wayland2, Wayland EGL External Platform library
Version 2 that works with NVIDIA drivers 560 and later.
This is a new implementation of the EGL External Platform Library
for Wayland (EGL_KHR_platform_wayland), using the NVIDIA driver's
new platform surface interface (Dma-buf-based), which simplifies
a lot of the library and improves window resizing.
This library can be installed alongside the previous egl-wayland
implementation (graphics/egl-wayland).
The new library has a higher selection priority by default,
so if both are present, then a 560 or later driver will select
the new library, and an older driver will fall back to the old
library.
