Update ODL version

[ElizabethOkerio]

Updated the ODL version to 8.0.0-preview.3. Since 8.0.0-preview.3 had some breaking changes, I've also made some updates like:

1. Getting rid of the IContainerBuilder and using Microsoft.Extensions.DependencyInjection instead.
2. Removed references to ODataSimplifiedOptions and used ODataMessageReaderSettings instead since we got rid of this class in ODL 8.0.0-preview.3
3. I've also made changes to ODataError's ErrorCode to Code and the way the ODataInnerError is initialized from new ODataInnerError { Message = ConvertModelStateErrors(modelStateError) }; to new Dictionary<string, ODataValue> { { "Message", new ODataPrimitiveValue(ConvertModelStateErrors(modelStateError)) } });

This PR also updates Microsoft.AspNetCore.OData version to 9.0.0.preview-1

The change is straightforward and looks good to me
