arch/risc-v: Fix incompatible pointer types in vector context switching

The riscv_savevpu/restorevpu functions were using 'uintptr_t *' for vector registers, but 'tcb->xcp.vregs' is defined as 'uintreg_t *'. This mismatch caused compilation errors on GCC 13+ due to incompatible pointer types. This patch aligns the parameter types to 'uintreg_t *'.
