Recover automated builds via GitHub Actions (#579)

* Adds latest work on actions for continuous integration.

* Change deploy branch to "Cog".

* Try Newspeak builds.

* Also build for pull_request; only deploy on push. [ci skip]

* Setup all main builds for Linux, macOS, and Windows. Sketch workflow for Linux32xARMv6 (not functional). Adds extra workflow for not-so-common VM flavors.

In linux install scripts, replace deprecated "--force-yes" with "--allow-unauthenticated".

* Quick-fix generated FT2Plugin to compile in Linux. Note that code generation does currently not work for that plugin.

* Quick fix to make squeak.cog.v3 build again on Linux32x86. Do not set or use endOfJITZone. This might not be what we actually want.

* [ci skip] Another quickfix for making the rather old EventsHandlerPlugin compile on Linux. Where are its Slang sources located anyway?

* Setup ARM builds for Linux. Remove obsolete build files for TravisCI, AppVeyor, Bintray.

* In all main "Build for *" workflows, add workflow_dispatch to build artifacts for release candidates per tag.
