GDScript: Add warnings that are set to error by default
...
- Adds a list of default levels for all warning so they can be set
individually.
- Add warnings set by default to error for:
- Using `get_node()` without `@onready`.
- Using `@onready` together with `@export`.
- Inferring a static type with a Variant value.
- Overriding a native engine method.
- Adjust how annotations to ignore warnings are treated so they also
apply to method parameters.
- Clean up a bit how ignored warnings are set. There were two sets but
only one was actually being used.
- Set all warnings to the `WARN` level for tests, so they they can be
properly tested.
- Fix enum types in native methods signatures being set to `int`.
- Fix native enums being treated as Dictionary by mistake.
- Make name of native enum types use the class they are defined in, not
the direct super class of the script. This ensures they are always
equal even when coming from different sources.
- Fix error for signature mismatch that was only showing the first
default argument as having a default. Now it shows for all.

the property is read-only.

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".

Improve dictionary printing to avoid confusion with arrays
...
- Add leading and trailing spaces within dictionaries, as the `{}`

with array-based properties.

fix(gdscript): Infer type from preload const
...
When resolving the type of the attribute from the variant, the result_type.kind was overritten for no reason.
It is assumed that this only needs to be done, if the variant value is not valid to have any kind here.

The `%` is used in scene unique nodes. Now `%` can also be used instead
