Merge #12572: [script] lint-whitespace: find errors more easily

0fbed98e42 [script] lint-whitespace: improve print linenumber (Akio Nakamura)

Pull request description:

  Before this PR, the linenumber infomaition is output if trailing-space or tab code was found, but the output occurence is only per a file.
  This PR separates the output timing of file name and line number.
  As a result, users will find where they need to fix more easily.

  example:

  0) git diff
  ```
  diff --git a/dummy.txt b/dummy.txt
  index c0ce4d776..aebbdb88d 100644
  --- a/dummy.txt
  +++ b/dummy.txt

  +1
  +       2
  @@ -8,2 +8,2 @@
  -8
  -9
  +       8
  +9
  ```

  1) before this PR - Is there "9 " in second line? It may lead to be misunderstood.
  ```
