RFR: 8310901: Convert String::newStringNoRepl with Latin-1 to String::newStringLatin1NoRepl [v2]

[Glavo]

> Added a new method `newStringLatin1NoRepl` to the `JavaLangAccess`.
> 
> Reasons:
> 
> * Most use cases of `newStringNoRepl` use `ISO_8859_1` as the charset, creating a new shortcut can make writing shorter;
> * Since all possible values of `byte` are legal Latin-1 characters, `newStringLatin1NoRepl` **will not throw `CharacterCodingException`**, so users can make the compiler happy without using useless try-catch statements.
