perf: More efficient calling frame detection

[maximilianruesch]

Using inspect.getmodule is overkill when all you are trying to retrieve is the name of the module (you can access that through the file-global __name__ as well). At the same time, inspect.getmodule accesses the file cache of the Python interpreter, potentially doing a lot of IO. During tracing workloads, calling frame detection is run for most expressions for purposes of nice error messages, and thus the inspect.getmodule is called in a rather hot loop. Any improvements here are vital for tracing performance.
