主题: [PATCH-V2] Fix Setup numeric default value incorrect issue

When default/manufacturing flag get removed from numeric varid, it can't
get default value from StructurePcd in

'UpdateDefaultSettingInFormPackage'

function since there is no EFI_IFR_DEFAULT_OP opcode in IFR file. Add a
chance to get numeric default value from StructurePcd in the case that
numeric minimum value will be used as default value.
