drivers/efi: add optional ESRT-friendly coreboot table tag

EFI System Resource Table (ESRT) is an informational structure that
reports basic details about current system or device firmware.  This is
chiefly used to perform firmware updates.

New CONFIG_DRIVERS_EFI_FW_INFO is off by default, enabling it adds
DRIVERS_EFI_FW_{GUID,VERSION,LSV} to be used to specify firmware
version/update information.

Existing forms of versions wouldn't be sufficient because there is no
universal way of converting string versions to 32-bit unsigned integers
and there are no GUIDs or lowest supported versions.
