Subject: [PATCH 1/2] Brewfile: install the latest CMake

Earlier we had trouble with CMake 3.20, and reverting to 3.16
worked around the problem. However this version is no longer
available in homebrew, so the `brew bundle` step is failing
in github ci. Try installing the latest version instead.

Currently that's CMake 3.22.1.

Subject: [PATCH 2/2] github actions: add build description

Add basic builds on Ubuntu and macOS hosts for Github's CI
automation. Each builds with either GNU Autotools, CMake,
or the plain Makefile, and then builds the documentation.

This gives some feedback on pull requests submitted
through github.

Based on similar code from libopusenc, borrowing steps
from the ci scripts directory and .travis-ci.yml.
