Subrata Banik 3306f37fd6 lib: Add new argument as ddr_type to smbios_bus_width_to_spd_width()
Add DDR5 and LPDDR5 memory type checks while calculating bus width
extension (in bits).

Additionally, update all caller functions of
smbios_bus_width_to_spd_width() to pass `MemoryType` as argument.

Update `test_smbios_bus_width_to_spd_width()` to accommodate
different memory types.

Create new macro to fix incorrect bus width reporting
on platform with DDR5 and LPDDR5 memory.

With this code changes, on DDR5 system with 2 Ch per DIMM, 32 bit
primary bus width per Ch showed the Total width as:

Handle 0x000F, DMI type 17, 40 bytes
Memory Device
	Array Handle: 0x0009
	Error Information Handle: Not Provided
	Total Width: 80 bits
	Data Width: 64 bits
	Size: 16 GB
	...

BUG=b:194659789
Tested=On Alder Lake DDR5 RVP, SMBIOS type 17 shows expected `Total Width`.
