mb/google/hatch: Add support for variant_memory_sku()

This change adds support for variant_memory_sku() that allows variant
to return memory SKU ID. Current implementation of memory_sku() is
renamed to weak implementation of variant_memory_sku(). Functionally
this change should be the same as before for all hatch variants. This
function will be overriden by helios in a follow-up CL.
