8312489: Increase jdk.jar.maxSignatureFileSize default which is too low for JARs such as WhiteSource/Mend unified agent jar

[gnu-andrew]

The security fix, JDK-8300596, introduced a maximum size for signature-related files in JAR files, via the jdk.jar.maxSignatureFileSize property. The default value of 8MB has since proven to be too low for some JARs in general use. This change doubles it to 16MB, while still being much lower than the previous MAX_ARRAY_SIZE value of Integer.MAX_VALUE - 8

This pull request contains a clean backport of commit e47a84f2 from the openjdk/jdk repository.

The commit being backported was authored by Hai-May Chao on 31 Jul 2023 and was reviewed by Sean Mullan and Matthias Baesken.

@gnu-andrew I think we should do this in jdk11u to make it part of the October update (as it is for OpenJDK 17 and 21). If you agree, please transplant the PR to jdk11u.

It's in the January 17 update (17.0.10) for both us and Oracle. Also, I don't think this is a critical fix. There is an easy workaround by setting the property explicitly.

OK then, I just thought the symmetry to JDK17 would be nice. But as you say, it's not that critical.
