cpu/microcode: Remove EXTERNAL / ADDED_DURING_BUILD variables 

There has been a concerted effort to clean up coreboot's microcode
handling that has included a move away from coreboot-specific
microcode file collections.  As a result, the ability to specify
a single microcode file to be added to the image is of less utility
than before.

NOTE: This patch remove the built-in external microcode feature,
however the user can still specify no microcode during build and
manually add the correct microcode file(s) to the CBFS image after
the build is complete.

Select this option if you want to include an external file containing
the CPU microcode. This will be included as a separate file in CBFS.
A word of caution: only select this option if you are sure the
microcode that you have is newer than the microcode shipping with
coreboot.
The microcode file may be removed from the ROM image at a later
time with cbfstool, if desired.
