Light up Span with Vector512 code paths.

[anthonycanino]

This task is for optimizing Span with Vector512 code paths. We will likely target Span.IndexOf as a first potential Vector512 code path for Span. This task will be updated with a list of methods in Span that we will likely target (and for each of its specialized implementations, e.g., Char and Byte).
