Add microcode blob processing

Browse Source 
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.
