Run `git cl format --full` on the C++ files in system_wrappers/

Specifically, this CL was generated by the following shell commands:

  cd system_wrappers
  for f in $(find . -type f | grep -E '[.](h|cc)$'); do echo >> $f; done
  git cl format --full

Followed by a revert of the changes to asm_defines.h since that file
is assembly and not C++, and a manual edit to clock.cc to add some
blank lines in the #include list to prevent `git cl format` from
sorting <MMSystem.h> before "rtc_base/win32.h".

I needed to do this because otherwise `git cl format` introduces a lot
of unrelated formatting changes in other CLs that move these files
(since `git cl format` will try to re-format all lines of a moved
file).
