refactor(profiling): make python_stack local and non static (#15801)
34146cf 
## Description

https://datadoghq.atlassian.net/browse/PROF-13364

This PR makes the `python_stack` variable non global (and non static) so
that its lifetime is easier to understand and to reason about. This
change is trivial as `python_stack` is already at the moment used
exactly like a local variable would be.
Since it is used by many parts of the Thread unwinding logic, I have
made it part of the `ThreadInfo` fields, so that each `ThreadInfo`
method can easily use it. Methods outside `ThreadInfo` access it using a
reference argument.

_This is part of a broader effort to get rid of statics and globals in
the Python Profiler._
- #15801
- #15806
- #15805

## Performance

Running the Profiler with those changes under the Full Host Profiler
shows no noticeable CPU time change (which could have happened, at least
marginally, since we have changed the semantics around and lifetime of
`FrameStack` objects).

refactor(profiling): remove some globals (#15805)
47ec4d1 
## Description

This PR removes several global variables we currently have and don't use
(from when we moved echion to dd-trace-py) and replaces a global variant
`runtime` (which was set to `&_PyRuntime`) with a local one instead.

_This is part of a broader effort to get rid of statics and globals in
the Python Profiler._
