cpu/microcode: Remove EXTERNAL / ADDED_DURING_BUILD variables

Browse Source 
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.
