Merge #2806: [Tools] Sanitize existing clang-format rules

472a423 Sanitize existing clang-format rules (Fuzzbawls)

Pull request description:

  Removes un-necessary extra whitespace, set explicit values instead of implied values for some rules, and update the standard to c++14.

  Updated the following rules to their new names:
  - `AlignEscapedNewlinesLeft` -> `AlignEscapedNewlines`
  - `IndentFunctionDeclarationAfterType` -> `IndentWrappedFunctionNames`

  Removed the following rules as they are un-necessary:
  - `Penalty*`: since we don't enforce a line length
  - `TabWidth`: since we don't use tabs
