MdePkg/SmBios.h: Add two additional DWORD for smbios 3.3.0 type17

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2482

Refer to DSP0134_3.3.0.pdf, there are two additional DWORD added
for type 17. One is "Extended Speed", the other is "Extended
Configured Memory Speed". The lack of these field may cause strange
error in some operating systems.
