Ben Pastene b5c6726e71 Enforce formatting of all py files under //testing/
Some subdirs have their own .style.yapf files (like
//testing/pytype_common/), but most do not. This has lead to a lot of
python code in //testing/ naturally being developed with no
consistent styling. This can make things a little hard to read when
put in the context of other py code throughout the repo that's much
more consistent.

So this:
- adds a basic //testing/.style.yapf file
- adds another testing/trigger_scripts/.style.yapf file that's similar
  but sets indent to 4, since the code in that dir currently uses
  4 indents
- reformats everything
- adds a presubmit checkout to //testing/PRESUBMIT.py to enforce that
  things stay formatted
