Don't end ext_wrappers.gen.inc macros with a backslash-newline

[Faless]

Fixes warning when including ext_wrappers.gen.inc:

godot-cpp/gen/include/godot_cpp/core/ext_wrappers.gen.inc:181:148: warning: backslash-newline at end of file

Thanks!

However, I'm not sure this is right fix

All the #define's look like:

#define MODBIND0( m_name) \
virtual void _##m_name()  override; \

That second line probably shouldn't even end with a \ in the first place. Could we just remove it in the s variable at the start of generate_mod_version()?

Ah, indeed, that is not needed, I was too focused on the fix that I didn't think of it 😅 .

Fixed, thanks!
