Attaching Tracer and Backtracer to all thread

[UnknownAPI]

I've noticed Im missing a lot of calls happening in different threads. It can be tricky to attach to threads that haven't been created yet. Is there a way to Trace assemblies across all threads?

Currently, only one thread per Il2Cpp::trace can be traced; however it is certainly possible to support multiple threads. Frida traces all the invocations by default, and it's frida-il2cpp-bridge that filters out the invocations.
A side effect of having multiple (or all) threads is the output in the console could be messier (e.g. the thread id should be added to disambiguate the invocations)

Would it be more logical to set the default behavior to trace on all threads and introduce a FilterThread method in the Tracer class, instead of having a single thread selector?
