Windows GUI: Add evergreen online/stub installer

[cjee21]

Add a version-less evergreen online/stub installer that will install the latest available suitable version for all Windows versions and architectures.

Also update the versioned online/stub installer to be consistent with the version-less one and simplify it.

Note: the evergreen online/stub installer is not working as intended because https://mediaarea.net/mediainfo_check/version.txt is returning changelog.bin instead of version.txt.

Update: the evergreen online/stub installer is now working as intended since the server is now serving the expected file.

So the only thing is whether we want to add signature verification. If yes, need to add the third party NSIS plugin DLL to the repository containing NSIS first.

So the only thing is whether we want to add signature verification.

I like the maximum balance between security, file size and dev time, if you consider that it is fine for you to add it I take it ☺️.

If yes, need to add the third party NSIS plugin DLL to the repository containing NSIS first.

Which NSIS plugin DLL?

Which NSIS plugin DLL?

As I mentioned earlier here, there are two possible plugins that I know of that should work. As far as I know, NSIS does not have built-in signature verification features so third party plugin is needed. The plugins basically calls Windows built-in verification features.

It helps about maintenance.
I have a preference for the Mozilla one, easy to add to the source code and we built it.
Can you start without our repo having the binary?

I can try to compile that and add the verification to our script and see if it works first.

Done adding digital signature verification using the Mozilla CertCheck plugin.

Both online installers are still under 100KiB.

The source code for the plugin can be obtained from:
https://github.com/mozilla/gecko-dev/tree/master/other-licenses/nsis/Contrib/CertCheck

The pre-built and digitally signed plugin DLL can be obtained from:
