One Copyright Update to rule them all As many open source projects have started doing it, we're removing the current year from the copyright notice, so that we don't need to bump it every year. It seems like only the first year of publication is technically relevant for copyright notices, and even that seems to be something that many companies stopped listing altogether (in a version controlled codebase, the commits are a much better source of date of publication than a hardcoded copyright statement). We also now list Godot Engine contributors first as we're collectively the current maintainers of the project, and we clarify that the "exclusive" copyright of the co-founders covers the timespan before opensourcing (their further contributions are included as part of Godot Engine contributors). Also fixed "cf." Frenchism - it's meant as "refer to / see".

Style: Partially apply clang-tidy's `cppcoreguidelines-pro-type-member-init` Didn't commit all the changes where it wants to initialize a struct with `{}`. Should be reviewed in a separate PR. Option `IgnoreArrays` enabled for now to be conservative, can be disabled to see if it proposes more useful changes. Also fixed manually a handful of other missing initializations / moved some from constructors.
