fna3d: 25.02 -> 25.10

Upgrade FNA3D to version 25.10.
25.05 fixes CMake 4.0 compatibility.
25.03 builds against SDL3 by default. As I'm uncertain of whether this
is a non-breaking change, I've opted to default to building against SDL2
still for nixpkgs (at least for now to get the CMake 4.0 incompatibility
fixed).
Other changes seem to be non-breaking.
