Fix some minor bugs on PCD schema according to final schema email send by Larry
1) In <PcdData> of <PcdBuildDefinition>, MaxDatumSize should be added;
2) In <PcdData> of <PcdBuildDefinition>, the number of <Value> should be [0..1] but not [0..n];
3) The max occurs of <SkuId> in <DynamicPcdBuildDefinitions> should be 1;
