The engine uses the names `int` and `float` to refer to the 64-bit types, so in the bindings generator we have a hardcoded conversion for those types. But this type conversion should not be used for metadata. Even though the underlying type should still be 64-bit for interop, metadata is meant to specify the correct type to expose. So if metadata says `float` it means the type is really meant to be a 32-bit `float` and not `double`. Other hardcoded type conversions (`int` and `Nil`) won't ever be metadata. This change corrects the `float` type, to use the right type in the generated C++ code. Before we were always using `double` due to this type conversion. (cherry picked from commit 4829199)

Was using CPPFLAGS, but should use the explicit scons CCFLAGS which makes it clear they are applied to both the C and C++ compiler. CPPFLAGS was also fine (they are preprocessor flags, also applied to both C and C++), but we should try to stay consistent with what we do in Godot. (cherry picked from commit f36acd8)
As was fixed with godotengine/godot#91208 (cherry picked from commit 7b31f39)
(cherry picked from commit 92ace04)
