Intel microcode files can contain an extended signature table after the
main payload, listing additional processor signatures and platform flag
combinations that are covered by the same microcode blob.
ucode-split was only reading the primary header signature when naming
output files and ignored the extended table entirely. As a result,
processors whose signature appeared only in an extended table entry had
no matching split file in ${DATADIR} and therefore no microcode via
cpucontrol(8).
This affected a number of CPU families in the current release, including
Raptor Lake (06-bf-02/05/06/07, Core Gen13/Gen14), Sapphire Rapids
steppings E0-E3 (06-8f-04 through 06-8f-07), Arrow Lake-H (06-c5-02),
Panther Lake (06-cc-02/03), and others.
Extend ucode-split to read the extended signature table and write an
additional output file for each entry.
