style(*): add numerous JSCS rules to unify code-styles in the tree

Changes:

  - add rule requireSpaceBeforeBlockStatements (require space before brace when opening block statement)
  - add operators to rule disallowSpaceAfterPrefixUnaryOperators (no space after prefix inc/dec ops)
  - add rule disallowSpaceBeforePostfixUnaryOperators (no space before postfix inc/dec ops)
  - add rule disallowSpacesInsideArrayBrackets (array literals no longer padded with spaces)
  - add rule requireCommaBeforeLineBreak (line can't start with comma token)
  - add rule validateLineBreaks (require LF linebreaks)

Closes #9792
