ArmPkg/SmbiosMiscDxe: Adjust the priority of getting firmware version 

The BIOS Firmware Version in the SMBIOS Type 0 can be fetched from
the fixed PcdFirmwareVersionString or platform specific OemMiscLib.
In fact, the support from OemMiscLib comes into play when the firmware
version may be modified at boot time for extended information.
Therefore, the priority of getting the version from OemMiscLib should
be higher.

In case there is no modification in the OemMiscLib, we have to keep
HII string STR_MISC_BIOS_VERSION empty or 'Not Specified'
to indicate that the firmware version should be fetched from
the PcdFirmwareVersionString.
