Update GitHub Actions config to switch Ubuntu 16.04 jobs to Docker containers.

The Ubuntu 16.04 environment is scheduled to be removed from GitHub Actions
in September 2021. Migrate those jobs to Docker containers or Ubuntu 18.04.

Also, added some older compilers. Ported CMake tests from Travis CI.

Based on https://github.com/boostorg/core/pull/95.
Closes https://github.com/boostorg/core/pull/95.
