[Feature Request] Add Python debug builds with Py_DEBUG flag

[XuehaiPan]

Description:
Describe your proposal.

Add Python debug builds with Py_DEBUG flag by setting --with-pydebug and --with-trace-refs configure options.

Justification:
Justification or a use case for your proposal.

Some advanced Python development features require the Python executable to be built with extra configure flags. For example:

• PYTHONDEBUG (command line option -d) requires --with-pydebug.
• -X showrefcount requires --with-pydebug.
• PYTHONDUMPREFS requires --with-trace-refs.
• PYTHONDUMPREFSFILE=FILENAME requires --with-trace-refs.

Reference:

There is a Ubuntu package python-dbg built with debug flag.

Are you willing to submit a PR?

Yes
