    gdb/python-config: replace deprecated distutils.sysconfig
    
    When running the gdb/configure script on ubuntu 22.04 with
    python-3.10.4, I see:
    
        checking for python... no
        checking for python3... /usr/bin/python3

    The distutils module is deprecated as per the PEP 632[1] and will be
    removed in python-3.12.
    
    This patch migrates gdb/python/python-config.py from distutils.sysconfig
    to the sysconfig module[2].
    
    The sysconfig module has has been introduced in the standard library in
    python 3.2.  Given that support for python < 3.2 has been removed by
    edae3fd6600f: "gdb/python: remove Python 2 support", this patch does not
    need to support both implementations for backward compatibility.
    
    Tested on ubuntu-22.04 and ubuntu 20.04.
