Added ValidateAndAdapt Methods for Property Validation

[haritha99ch]

This PR introduces two new extension methods, ValidateAndAdapt, for the Mapster library. These methods ensure that all properties in the destination type either exist in the source type or are configured in Mapster. If a property does not exist and is not configured, an exception is thrown.

The PR includes:

• Implementation of ValidateAndAdapt methods.
• Test cases that cover different scenarios.

Usage

public static class ReportSelectors
{


    #region Selectors

    /// <summary>
    ///     Select WitnessId
    /// </summary>
    /// <returns>new <see cref="PermissionsToEditProps" />{ WitnessId = report.WitnessId }</returns>
    public static readonly Expression<Func<Report, PermissionsToEditProps>> PermissionsToEdit =
        e => e.ValidateAndAdapt<Report, PermissionsToEditProps>();

    /// <summary>
    ///     Select ModeratorId, Status
    /// </summary>
    /// <returns>new <see cref="PermissionsToModerateProps" />{ ModeratorId = report.ModeratorId, Status = report.Status }</returns>
    public static readonly Expression<Func<Report, PermissionsToModerateProps>> PermissionsToModerate =
        e => e.ValidateAndAdapt<Report, PermissionsToModerateProps>();

    /// <summary>
    ///     Select WitnessId, Status
    /// </summary>
    /// <returns>new <see cref="PermissionsToViewProps" />{ WitnessId = report.WitnessId, Status = report.Status }</returns>
    public static readonly Expression<Func<Report, PermissionsToViewProps>> PermissionsToView =
        e => e.ValidateAndAdapt<Report, PermissionsToViewProps>(PermissionsToViewPropsAdapter.Config);

Hello @haritha99ch
Is this a PR, about adding a new feature, or do you want to solve some existing problem?
For example:
Unexpected null or default value in TDisitination after adaptation?

[haritha99ch]

Hello @DocSvartz
I’m not entirely sure if there are existing validations in the library. If there are, then this is just an alternative solution to a problem. However, if there aren’t any validations, this could be considered as a new feature. I just wanted to share a fix, and I hope this can certainly be improved.

[DocSvartz]

This is a great addition.
You mentioned RecordType in the description.
And I wanted to make sure that the starting point for this PR was not any mapping problems to RecordType.

Thank you for your feedback @DocSvartz.
and yes, this is not any mapping problems to RecordType.
