Add microcode blob processing
When microcode storage in CBFS is enabled, the make system is supposed to generate the microcode blob and place it into the generated ROM image as a CBFS component. The microcode source representation does not change: it is still an array of 32 bit constants. This new addition compiles the array into a separate object file and then strips all sections but data. The raw data section is then included into CBFS as a file named 'microcode_blob.bin' of type 0x53, which is assigned to microcode storage.
