Support for Godot 3.5?

[alex-pahdo]

Godot's Thread was overhauled in January 2021. Static function Thread::create has been replaced with instance call thread.start, among other things.

Until updated to match the new implementation, errors like this block builds:

zprofiler/server/zprofiling_server.cpp:28:20: error: no member named 'create' in 'Thread'
        _thread = Thread::create(c_thread_func, this);

Depending on priorities, I might have time to write the update myself. Is this project active and accepting PRs?
