cpu: Rename CPU_MICROCODE_IN_CBFS to SUPPORT_CPU_UCODE_IN_CBFS

CPU_MICROCODE_IN_CBFS was designed to mean that loading microcode updates
from a CBFS file is supported, however, the name implies that microcode is
present in CBFS. This has recently caused confusion both with contributions
from Google, as well as SAGE. Rename this option to
SUPPORT_CPU_UCODE_IN_CBFS in order to make it clearer that what is meant is
"hey, the code we have for this CPU supports loading microcode updates from
CBFS", and prevent further confusion.
