arch/x86/smbios.c: Add SMBIOS type 17 for empty DIMM slots

1. Add Kconfig SMBIOS_TYPE17_EMPTY_SLOT that can create SMBIOS
type 17 tables for empty DIMM slots that don't have DIMM installed,
this feature is desirable for server platforms.
Mainboard can override mainboard_check_slot_exist to avoid
creating empty DIMM tables that don't exist on the board.

2. SMBIOS type 19 and 20 need to ignore meminfo->dimm_cnt array
boundary check when SMBIOS_TYPE17_EMPTY_SLOT is selected,
because meminfo->dimm would contain not only the installed DIMM.

3. Avoid creating type 20 when the DIMM size is zero.
