Dennis Kempin ee56b2ddec Add presubmit script
Consolidates the utility scripts from bin/ into tools/.
Adds a 'presubmit' utility script to run a set of checks and
tests.

This won't be a git hook, but can be manually used to verify
changes before uploading.

BUG=b:199951064
TEST=./tools/presubmit --quick
./tools/dev_container ./tools/presubmit
