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.
