Implement the standard IDisposable pattern in unsealed classes

[airbreather]

A few classes implement System.IDisposable, but they do so without using the standard pattern. See CA1063:ImplementIDisposableCorrectly, including its "See Also" links, for a description of this pattern.

I'm wrapping up what I intend to submit for the native memory array implementation, and in my self-review, I noticed that I don't have a finalizer on the type, which got me thinking about this.

The types I see that directly implement System.IDisposable are:

• Reminiscence.Arrays.ArrayBase<T>
• Reminiscence.Collections.List<T>
• Reminiscence.Indexes.Index<T>
• Reminiscence.IO.MemoryMap
• Reminiscence.IO.MappedAccessor<T>

Something like that could be adapted?
