Use standard IDisposible implementation

[AristurtleDev]

Description

As I'm going through the code base and updating it to close out issues, I'm coming across classes that don't implement IDisposable in the standard pattern when the class or interfaces are meant to be inherited. The standard implementation should be

public class Foo : IDisposable
{
    public bool IsDisposed { get; private set; }

    ~Foo() => Dispose(false);

    public void Dispose()
    {
        Dispose(true);
        GC.SuppressFinalize(this);
    }

    protected void Dispose(bool disposing)
    {
        if (IsDisposed)
        {
            return;
        }

        if (disposing)
        {
            // Disposed managed resources
        }

        // dispose unmanaged resources

        IsDisposed = true;
    }
}

As making this change for several classes would be considered a breaking change, I'm using this issue to keep track and as a reminder so they can be included with the next major SemVer release.
