riscv: move kaslr_offset() to page.h as a static inline function

The kaslr_offset() function is a simple accessor that returns
kernel_map.virt_offset. This commit change also ensures that kaslr_offset()
is consistently available across various kernel configurations without
requiring explicit linkage to mm/init.c.
