PlayStation: use Color.GetR/GetG/GetB extensions for byte conversion

Addresses DarthAffe's review feedback on PR DarthAffe#454 — the manual
(byte)Math.Clamp((int)Math.Round(c * 255.0), 0, 255) pattern in both
update queues is replaced with the project's standard Color.GetR /
GetG / GetB extensions, which delegate to GetByteValueFromPercentage
in RGB.NET.Core. That gives consistent rounding behaviour across the
codebase and matches the convention every other provider uses.
