lib/libpayload: Replace strapping_ids with new board configuration entry

Browse Source 
There are currently 3 different strapping ID entries in the coreboot
table, which adds overhead. The new fw_config field is also desired in
the coreboot table, which is another kind of strapping id. Therefore,
this patch deprecates the 3 current strapping ID entries (board ID, RAM
code, and SKU ID), and adds a new entry ("board_config") which provides
board ID, RAM code, SKU ID, as well as FW_CONFIG together.
