Fix broken SwANGLE documentation link
We no longer support building SwANGLE from a SwiftShader checkout, and
the documentation was already removed but a link remained in README.md.
This change just replaces that with a brief mention of ANGLE.

SwiftShader is a high-performance CPU-based implementation of the Vulkan graphics API<sup>1</sup><sup>2</sup>. Its goal is to provide hardware independence for advanced 3D graphics.
-> NOTE: SwiftShader's OpenGL ES implementation is no longer supported, and will be removed. Read more about our recommendation to use [ANGLE on top of SwiftShader Vulkan here](docs/ANGLE.md) (aka. "SwANGLE").
