Implement Send and Sync for PhantomVar

[ttencate]

The type contains no data, so this is guaranteed to be safe.

These are auto traits that are already implemented:

• https://godot-rust.github.io/docs/gdext/master/godot/prelude/struct.PhantomVar.html#impl-Send-for-PhantomVar%3CT%3E
• https://godot-rust.github.io/docs/gdext/master/godot/prelude/struct.PhantomVar.html#impl-Sync-for-PhantomVar%3CT%3E

But I guess you change this to any T, without the bounds?

Exactly.

My use case is to have a struct that implements Send, which contains some kind of string. My attempted solution was:

struct MyStruct {
    text_string: String,
    #[var(get = get_text)]
    text: PhantomVar<GString>,
}

This didn't work because GString does not implement Send, and therefore PhantomVar<GString> also doesn't.

Thanks a lot!
