[ResourceTiming]: Update WPTs concerning opaque origins

Both TAO-null-opaque-origin.html and TAO-case-insensitive-null-opaque-origin.sub.html test the Resource Timing API when resources are fetched from an opaque origin context. This change updates those tests to conform to wpt/resource-timing/CodingConventions.md.

+<h1>Description</h1>
+<p>This test validates that, for a cross origin resource, the timing allow
+check algorithm will correctly distinguish between 'null' and 'Null' values in
+the Timing-Allow-Origin header. An opaque origin's serialization is the string
+"null" and the timing allow origin check needs to do a case-sensitive comparison
+to the Timing-Allow-Origin header.
