Simplify prettier setup (#418)

Use a global command that checks the whole repo to avoid having to repeat the
complex commands in each project, and to prevent some files from escaping the
check.

NOTE: This removes per-project `npm run format` and `npm run check-format`.
Use `rush format` and `rush check-format`.
