refactor: refactor CI by separating on several files

[Gigas002]

Mostly moving stuff around, but minor changes included:

• build three patterns: all-features, default-features, minimal (with just png feature)
• separate coverage reports for libwayshot and wayshot

Also, left unchanged, but in #234 @Shinyzenith mentioned that probably we don't need to distribute binaries with release, maybe we should remove this part of job? If not, we should probably add all-features to it? Or distribute several flavors? Or just the default? I'm not sure what'd be best here.

Seems good for me! I have thought this ci is too long long ago
