smbios: Make SMBIOS type 3 enclosure type settable at runtime

smbios.h had already declared smbios_mainboard_enclosure_type so this
change defines it. It can be overridden in a mainboard so the enclosure
type can be set at runtime.

We have a mainboard that will be used in different enclosures and we are
planning on using a single BIOS image for all of the enclosures so it
will need to be set dynamically based on sku.

BUG=b:138745917
TEST=Built arcada firmware and verified via dmidecode that enclosure type
     is correctly set to "Convertible", then temporarily added a
     smbios_mainboard_enclosure_type to arcadas board file returning
     0x20 and verified with dmidecode that the enclosure type is
     "Detachable"
