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

[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.
