block: stub out and deprecated the capability attribute on the gendisk
The capability attribute was added in 2017 to expose the kernel internal
GENHD_FL_MEDIA_CHANGE_NOTIFY to userspace without ever adding a value to
an UAPI header, and without ever setting it in any driver until it was
finally removed in Linux 5.7.
Deprecate the file and always return 0 instead of exposing the other
internal and frequently renumbered other gendisk flags.
