Lenny Maiorani d144da3a62 LibGfx: Refactor Vector[2,3,4] to VectorN with specializations
`Gfx::Vector[2,3,4]` are nearly identical implementations. This code
redundancy does not follow the DRY (Don't Repeat Yourself) principle
leading to possible out-of-sync errors between the classes.

Combining these classes into a class template which can be specialized
for each needed size makes the differences obvious through
`constexpr-if` blocks and `requires` clauses.
