RFR: 8345936: Call ClassLoader.getResourceAsByteArray only for multi-release jar [v2]

[Calvin Cheung]

> This patch stores whether a jar is multi-release in the SharedClassPathEntry during CDS dump time.
> At runtime, it only calls ClassLoader.getResourceAsByteArray if the jar is a multi-release jar.
> As a result, the number of java calls is reduced.
> 
> Passed tiers 1, 3, 4 testing.
