[python] tracing some native values may throw

[clemos]

Hi 👋

I'm working on a personal project with Haxe + Spacy and stumbled upon this "bug".

When calling trace on a native python Spacy Token object, the program will throw:

TypeError: Argument 'other' has incorrect type (expected spacy.tokens.token.Token, got type)

The error occurs in python.Boot.toString1, at the following line, which checks if the traced value is the python "str" type:
https://github.com/HaxeFoundation/haxe/blob/development/std/python/Boot.hx#L195
which in turn calls this method:
https://github.com/HaxeFoundation/haxe/blob/development/std/python/Boot.hx#L226

It seems Spacy has some kind of comparison overloading that throws an error when attempting to compare a Token (and other types) to an unrelated object.

To make python.Boot.toString1 (and trace) more resilient, I propose that isMetaType generates:

type(v) == type and v == t

instead of just

v == t

and also to type t as Class<T> just in case.

What do you think ?
