arm64: select KASAN_VMALLOC for SW/HW_TAGS modes

Generic KASAN already selects KASAN_VMALLOC to allow VMAP_STACK to be
selected unconditionally, see commit acc3042d62 ("arm64: Kconfig:
select KASAN_VMALLOC if KANSAN_GENERIC is enabled").

The same change is needed for SW_TAGS KASAN.

HW_TAGS KASAN does not require enabling KASAN_VMALLOC for VMAP_STACK, they
already work together as is.  Still, selecting KASAN_VMALLOC still makes
sense to make vmalloc() always protected.  In case any bugs in KASAN's
vmalloc() support are discovered, the command line kasan.vmalloc flag can
be used to disable vmalloc() checking.

Select KASAN_VMALLOC for all KASAN modes for arm64.
