Merge #11573: [Util] Update tinyformat.h

Browse Source 
60b98f8 [Util] Update tinyformat.h (fanquake)

Pull request description:

  Updates `tinyformat.h` to commit c42f/tinyformat@689695c upstream. Including:
  8a2812d848
  5d9e05a347
  48e2e48789

  @achow101 mentioned that since upgrading to Ubuntu 17.10 (GCC 7), tinyformat had been throwing lots of -Wimplicit-fallthrough warnings. However fallthrough warnings should have been silenced by #10489. cc @theuni.

  The upstream commit to fix fallthrough warnings is in this PR https://github.com/c42f/tinyformat/pull/39.

  The last time tinyformat.h was updated in this repo was in #8274.
