Convert microcode to binary

Intel's microcode is a binary that has been converted to
an array of 32bit values. Instead of converting that back
to binary on every compile, just store the microcode as
a binary in the first place, and add that binary to CBFS.

This patch adds a script that takes all current Intel microcode.h
files and produces microcode.bin files. In addition, this patch
also adds all the microcode.bin files produced by the script.
