fabian giesen 7d8781778c Deprecate TVector2 operator <, >, <=, >= ...

2D vectors are not canonically ordered and having these operators results in very unfortunate interactions with generic code. In particular FMath::{Min,Max,Abs} on TVector2s compile but do not behave as one would expect.

Add explicit comparison methods as a replacement and deprecate uses of TVector2 overloaded relational operators since it's confusing and error-prone. Fix existing uses to avoid deprecation warnings. Several of these fixes are behavioral changes to fix what I am reasonably certain are bugs in the existing code - in particular, uses of FMath::{Min,Max,Abs} on TVector2s that almost certainly actually want TVector2::{Min,Max,GetAbs} instead.
