RFR: 8367129: Move input validation checks to Java for java.lang.StringLatin1 intrinsics [v3]

[Volkan Yazici]

> Moves input validation checks to Java for `java.lang.StringLatin1` intrinsics. While doing so, affected `java.lang.StringUTF16` methods needed to be updated due to relaxed checks at intrinsics. The javadocs of the touched methods are extensively overhauled.

Volkan Yazici has updated the pull request incrementally with two additional commits since the last revision:

 - Use `vmIntrinsics::*` to refer to intrinsics from Java
 - Improve vertical alignment in `vmIntrinsics.hpp`
