[issue22149] the frame of a suspended generator should not have a local trace function

[Xavier de Gaye]

New submission from Xavier de Gaye:

When tracing, the frame of a suspended generator should not have an f_trace function as there is no way to delete the frame f_trace attribute in that case even though
tracing may have been disabled.

The patch relies on the fact that whenever the generator is resumed, a 'call' tracing event is issued and the generator's frame f_trace is set again.
As expected, frames, including generators' frames, have their f_trace attribute cleared on the 'return' tracing event that is issued when the frame goes out of scope
or when the system's trace function has been removed.
