IDISP010 False warning when base method is abstract

[Emik03]

Classes like the standard library's MemoryManager<T> have an abstract dispose method, which cannot be called despite the lint asking for it to be invoked.

sealed class Manager : MemoryManager<byte>
{
    /// <inheritdoc />
    public override void Unpin() { }

    /// <inheritdoc />
    public override unsafe MemoryHandle Pin(int elementIndex = 0) => default;

    /// <inheritdoc />
    public override unsafe Span<byte> GetSpan() => default;

    /// <inheritdoc />
    protected override void Dispose(bool disposing) { } // <-- lint occurs here
}
