Message:

Increase resource load priority of async scripts from low to medium
​https://bugs.webkit.org/show_bug.cgi?id=222966

Reviewed by Zalan Bujtas.

Low priority loads may be delayed during parsing. We want async script to be immediately available when parsing
completes so 'medium' is the appropriate priority
