Zaggy1024 3cfe1f7542 LibGfx: Implement YUV->RGBA color conversion for CPU painting ...

Using the Rust yuv crate, eagerly convert from YUV to RGBA on the CPU
when a GPU context is unavailable.

Time spent converting an 8-bit YUV frame with this crate is better than
libyuv on ARM by about 20%, and on x86 with AVX2, it achieves similar
numbers to libyuv.
