RFR: 8318486: Rename JavaLangAccess.newString/getBytesUTF8NoRepl to FailFast

[Chen Liang]

Please review a patch that renames `JavaLangAccess::newStringUTF8NoRepl` and `getBytesUTF8NoRepl` to `newStringUTF8FailFast` and `getBytesUTF8FailFast` to accurately describe these APIs. This also renames other associated methods.

NoRepl means "no replication", which is not what these APIs are for. They instead expose the fail-fast construction fast-path in String, allowing `ZipCoder` to quickly throw encoding exceptions wrapped in `IllegalArgumentException` without going through decoders and encoders.

In addition, there is already `newStringNoRepl` and `getBytesNoRepl` in `JavaLangAccess` that actually avoids copying arrays for trusted usages, further increasing the confusion. Given these internal APIs are frequently used in recent contributions around improving string performance, I believe a rename of these APIs is necessary.

Pinging @cl4es for a review since you use this particular API the most often.
