.github: Add PR template

Adds a pull request template with important information to note in
the PR description and guidance on how to classify the PR.

A simple GitHub action is present that applies three labels based
on the boxes checked in the PR template:

- `impact:breaking-change`
- `impact:security`
- `impact:testing`

These provide several purposes.

1. Bring attention to the impact of the PR both for reviewers and
   consumers that reference the PR in the future during debug
   or integration.
2. Allow automated tools like those that create release notes to
   be able to highlight important changes.
3. Similarly, to allow PR searches to conditionalize the search on
   PRs with these tags present.
