ReadOnlySpan created from a null array does not return a null ReadOnlySpan

[steveharter]

Type of issue

Typo

Description

For the ReadOnlySpan<T>(T[]?) constructor that can take a null array, the doc says If the array is null, this constructor returns a null ReadOnlySpan<T>.

However, the method instead creates an empty span. A span, being a ref struct cannot be nullable. It should say "This method returns default when array is null." as described in the other constructor ReadOnlySpan<T>(T[], Int32, Int32).
