This header doesn't actually make use of MathUtil.h within itself, so this can be removed. Many other source files used VideoCommon.h as an indirect include to include MathUtil.h, so these includes can also be adjusted. While we're at it, we can also migrate valid inclusions of VideoCommon.h into cpp files where it can feasibly be done to minimize propagating it via other headers.
