The energy monitor declares a transition on an animated int property,
for which Property<int>::set_animated_binding_for_transition is called,
which in turn calls slint_property_set_animated_binding_helper. The
latter is overloaded for various property types, such as float, Color,
or Brush, and then calls specialized functions from ffi, such as
slint_property_set_animated_binding_(int|float|etc.).
slint_property_set_animated_binding_int uses i32 in Rust, which cbindgen
maps to int32_t, so the
slint_property_set_animated_binding_helper overload also uses int32_t.
Unfortunately, with esp-idf, int32_t is a distinct type from int, and
the overload resolution fails.
As remedy, this change uses c_int instead of i32 in the Rust ffi, which
maps to int.
This seems easier than changing Property<int> to Property<int32_t> :-)
... even if the old value holds the same value as the new value
This fixes test_cpp_bindings_two_way_priority_default
Also add a C++ unit test that tests the Property type specificaly
