util/cbfstool: Add AMD BIOS compression tool for PSP

Browse Source 
Add a utility to generate a compressed BIOS image for AMD Family 17h.

If the input is an elf file, the utility extracts the program portion
for compression.  Otherwise the file is compressed as-is.

In modern AMD systems, the PSP brings up DRAM then uncompresses the
BIOS image into memory prior to x86 beginning execution.  The PSP
supports a zlib engine, and interprets the first 256 bytes as a
header, where offset 0x14 containing the uncompressed size.  For
further details, see AMD Platform Security Processor BIOS Architecture
Design Guide for AMD Family 17h Processors (NDA only, #55758).

TEST=Use with WIP Picasso
