x86/sev: Use new AES-GCM library

The old AES-GCM library code is being replaced as part of an overhaul
that is adding support for all the common AES encryption modes with
consistent conventions.  The SEV code is the only user of the old
AES-GCM library.  Update it to use the new API instead.

Besides adjustments to the key struct name, function names, return
value, and parameter order, the only notable changes are:

- Replace the direct accesses to the auth tag length field (which should
  be considered private until someone truly needs it) with the
  AUTHTAG_LEN constant which is already defined in <asm/sev.h>.

- Replace kfree() with kfree_sensitive() on lines being changed anyway.
