kasan: add kasan.vmalloc command line flag
Allow disabling vmalloc() tagging for HW_TAGS KASAN via a kasan.vmalloc
command line switch.
This is a fail-safe switch intended for production systems that enable
HW_TAGS KASAN. In case vmalloc() tagging ends up having an issue not
detected during testing but that manifests in production, kasan.vmalloc
allows to turn vmalloc() tagging off while leaving page_alloc/slab
tagging on.
