Dynptr currently caps size and offset at 24 bits, which isn’t sufficient for file-backed use cases; even 32 bits can be limiting. Refactor dynptr helpers/kfuncs to use 64-bit size and offset, ensuring consistency across the APIs. This change does not affect internals of xdp, skb or other dynptrs, which continue to behave as before. Also it does not break binary compatibility. The widening enables large-file access support via dynptr, implemented in the next patches.
