RFR - JDK-8223775 String::stripIndent (Preview)

[Jim Laskey]

Please do a code review of the new String::stripIndent instance method. This instance method is being introduced to support JEP-355: Text Blocks, by removing incidental indentation from the text block content. The algorithm used is defined in the JEP and also described in the JBS entry.

Thank you.
