Add ignore_module/unignore_module commands to pdb

Feature or enhancement

Proposal:

Add two new commands to the Python debugger (pdb) to ignore and unignore specific modules when navigating frames.
Those commands allows to use wildcards to ignore submodules too.

• ignore_module [module_name] - Add modules to skip during debugging
• unignore_module [module_name] - Remove modules from the skip list

When debugging applications we often need to step through deep stack traces from third party libraries that are hard to navigate and makes focusing on our code harder, requiring to manually go up or down to find our code.

There is a similar implementation on ipython https://github.com/ipython/ipython/pull/14973

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere

Start by reviewing pdb's command handling and the related IPython implementation linked in the proposal, then check gh-139724 because work is already linked there. Done means pdb supports ignore_module and unignore_module, including wildcard module matching, and the behavior is covered by relevant tests.
