[PATCH 1/1] BaseTools: Copy PACKED definition from MdePkg Base.h

["gaoliming" <gaoliming@byosoft.com.cn>]

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=2938

MdePkg Acpi10.h definition depends on PACKED.
When structure PCD refers to Acpi10.h, build will fail,
because PACKED definition is missing in BaseTools BaseTypes.h.
