Only minor changes are required to make the kernel 64 bit compatible. Most of the changes are either DEBUG/printf formatting or different types for void pointer casting. The only other change is the type of the `data` member in priority_queue_node_t, as `data` must be able to store a pointer. For current architectures, the assumption `sizeof(unsigned int) == sizeof(void *)` holds, but not for 64 bit. Therefore, the type is changed to `uintptr_t', which has the same size for the current architectures, but can also store a pointer in 64 bits.

* priority_queue_t: Replaced `-1U` literal with PRIORITY_QUEUE_DATA_SIGNALING define * architecture.h: Added 64-bit * bloom.h: Fixed typedef for the hashfp_t function pointer * vfs.h: Increased default vfs buffer sizes for 64 bit * bytes.h: Check if socklen_t is already defined * ztimer: Use PRIxPTR format specifier
Fixed compilation errors for pointer casting.

Contribution description
Since #20154 still seems a bit too big to discuss properly, I decided to split it into smaller PRs.
This PR includes the changes to
core,sysanddriversto enable 64-bit support.The commits are part of this patch series
Testing procedure
All tests and applications should remain unchanged for existing platforms.
