Move packed key functions to their own file, in preparation for
introducing support for vb2_packed_key2.
Rename the awfully-named vb2_verify_fw_preamble2() function to
vb2_load_fw_premable(), since the new structs actually have a
vb2_fw_preamble2 struct and that would be very confusing.
Rename vb2_verify_fw_keyblock() to vb2_load_fw_keyblock(), so it
matches.
No functional changes, just renaming.

Compiling in the GBB magic number as is causes any tools that search for the
number to fail. This patch allows firmware to embed XOR'ed signature.
TEST=Booted Nyan in normal mode. FAFT:firmware_DevMode passes.

I'm breaking the last chunk of vboot2 into smaller pieces as I add
tests. This has the higher-level routines for verifying keyblock and
preamble.

I'm breaking the last chunk of vboot2 into smaller pieces as I add
tests. This has a bunch of misc routines like the dev switch logic
and GBB header parsing.
