Subject: [PATCH 1/2] ci: migrate from CircleCI to GitHub Actions

Replaces .circleci/config.yml with a GitHub Actions workflow that runs the
same build/test/bench steps across Go 1.15, 1.16, and stable. Actions are
pinned to commit SHAs with version tags as comments.

Subject: [PATCH 2/2] ci: chain apt commands and use $() in workflow

Chain apt-get update with the install via && so install is skipped if
update fails, and replace backtick command substitution with $() in the
test/benchmark PAYLOAD assignments.
