kasan, x86, arm64, s390: rename functions for modules shadow
Rename kasan_free_shadow to kasan_free_module_shadow and
kasan_module_alloc to kasan_alloc_module_shadow.
These functions are used to allocate/free shadow memory for kernel modules
when KASAN_VMALLOC is not enabled. The new names better reflect their
purpose.
Also reword the comment next to their declaration to improve clarity.
