This PR adds Chromium with webdriver to the Docker image, so it's now possible to run at least some subset of tests using Docker env.
Additionally, Alpine version has been bumped up, so recent version of Chromium can be used.
This removes the overly-complex docker-compose system and rewrites the
Dockerfile. It also changes the docker commands to those that specify a
user ID, so that build outputs are written as the current user.
Closes#4387 (failed docker build not detected in CI)
Issue #4619 (failed to build w/ docker)
Many devs using Shaka and wishing to compile the library are required to install all prerequisites on their machine. For docker devs, this is extremely bad as it requires installing Java and Python on OS.
This commit adds a basic configuration for quick compilation via Docker, without requiring any other prerequisites. Improvements can be made in order to allow all Shaka workflow inside Docker.
