Create polyvox_constexpr macros based on the detected features

Browse Source 
We now have a two new polyvox_ macros:

* polyvox_constexpr which is 'constexpr' is supported and '' otherwise
* polyvox_constexpr_const constexpr which is also 'constexpr' is supported
  but falls back to 'const' otherwise.

These macros should be safe to use liberally without worrying about which
compiler you're on.
