The annotation tests skipped their checks with -builtin or -fastproxy as
neither adds __annotations__ to the generated runtime objects. That is no
longer a reason to skip when -pyi is also used, as the annotations are then
in the generated stub file, but the stub lookup only worked for -builtin.
With -fastproxy a method is the flat C wrapper function, so its __qualname__
is Class_method instead of Class.method. Pass a fastproxy flag from each
runme down to the stub lookup so that such a name is split on the stub class
names only when it really is a flat name. Reword the comment explaining when
annotations_supported is false, which was misleading with -pyi.

A generated stub class with no wrapped members had an empty suite, which
is invalid Python syntax. Stubs could also refer to base classes from
%imported modules without importing the corresponding Python proxy
module, leaving those names unresolved.
Track whether each stub class emits a member and use an ellipsis when
its body would otherwise be empty. Collect modules referenced through
%import and emit them before declarations, using the same package and
relative import rules as the generated Python proxy.
Keep annotation tests active with -pyi by parsing annotations from the
generated stub instead of expecting them on runtime objects. Include
each generated .pyi file in multi-module Pyrefly checks.
Add Python 3.14 Linux CI configurations for -pyi -typehints with and
without -builtin.

Both function annotations and variable annotations are turned on using the
"python:annotations" feature. Example:
%feature("python:annotations", "c");
struct V {
float val;
};
The generated code contains a variable annotation containing the C float type:
class V(object):
val: "float" = property(_example.V_val_get, _example.V_val_set)
...
Python 3.5 and earlier do not support variable annotations, so variable
annotations can be turned off with a "python:annotations:novar" feature flag.
Example turning on function annotations but not variable annotations globally:
%feature("python:annotations", "c");
%feature("python:annotations:novar");
or via the command line:
-features python:annotations=c,python:annotations:novar
