These errors are very common when using an invalid property name
or calling on an object of the wrong type, and the previous message
was a bit cryptic for users.

Within a match statement, it is now possible to add guards in each
branch:
var a = 0
match a:
0 when false: print("does not run")
0 when true: print("but this does")
This allows more complex logic for deciding which branch to take.
Unfortunately it appears the virtual function checks in #77324 are not
trustworthy at runtime, because objects can have scripts attached, but
this information is not always available at compile-time. These checks
need to be removed.
The rest of the PR is still useful, making all method flags available to
the analyzer, so a full revert isn't necessary/desirable.
This reopens#76938, which will need another solution.
This PR does a small refactor of how method flags are handled in the GDScript analyzer.
This way, it adds support for the analyzer to use any of MethodInfo's flags, where previously
it could only use METHOD_FLAG_STATIC and METHOD_FLAG_VARARG.
As a side-effect, this also normalizes behavior between editor and release templates, which fixes#76938.
The tests added also brought a different issue to light, where using `super()` appears to generate a
return variable discarded on calling super's _init(), which doesn't have a return value. This should be
tackled in a different PR, which will have to change the output of this PR's tests.
Which allows editable data associated with a particular class instead of
the instance. Scripts with static variables are kept in memory
indefinitely unless the `@static_unload` annotation is used or the
`static_unload()` method is called on the GDScript.
If the custom function `_static_init()` exists it will be called when
the class is loaded, after the static variables are set.
This PR removes a check for whether a datatype is a meta type when
generating a datatype's to_string() result. This means that error
messages that fail to find the type will now print their class names,
which is much more useful when trying to identify errors.
Add functions to CoreConstant so enums can be properly deduced. Also add
the enums in release builds to make consistent with ClassDB enums and
avoid differences in script compilation between debug and release.
- 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.
- Consider PackedArrays non-shared since they are copied on C++/script
boundaries.
- Add error messages in the analyzer when assigning to read-only
properties.
- Add specific error message at runtime when assignment fails because
the property is read-only.
