Modernize InvertPSDMatrix with if constexpr

Use if constexpr for kSize checks in InvertPSDMatrix to allow for
dead-code elimination at compile time. This ensures that for small
fixed-size matrices, only the inverse() path is compiled, and for
larger or dynamic matrices, only the LLT path is compiled when
assume_full_rank is true.
