ci: Get rid of binaries submodule

[piotradamczyk5]

Fixes #896

This PR delete submodule for binaries and download them at runtime from release page based on os system

Test Plan

How do we know the code works?

macOs -> all should work by default because previously binaries were not copied on macOS
linux -> it download binaries from release page at runtime to <user_home>/.flank directory and unpack them
windows -> it works similar to linux version, however, full support will be available after #1134

All tests should work properly

Checklist

• Documented
• Unit tested
• Downloading binaries for Linux and Windows at runtime
• Create binaries release for Linux and Windows
• Update binaries assets after each change on binaries repo release page >> PR
• Delete submodule
• Update Github Actions to do not checkout submodules

Do we still need the old method?

[piotradamczyk5]

this is standalone without flank-scripts needed

[jan-goral]

The code looks well, but I would love to have this implementation in the java-library module linked to the test_runner as Gradle dependency, maybe not now, it could be in another PR.
Some of the code looks a little bit redundant according to flank-scripts, for example, utilities for unzipping & symlinks, probably also could be moved to another library module shared between download-binaries(?) and flank-scripts.

Yeah I think that we could do some shared module which has common logic for other modules, I will create a ticket for it

• Tested on windows, works!
