python3: update 3.9.7 -> 3.10.0

native and target 0001-Lib-sysconfig.py-use-libdir-values-from-configuratio.patch
replaced by native-only 0001-Lib-sysconfig.py-use-prefix-value-from-build-configu.patch
which is more reboust against upstream changes, and keeps target code unmodified.

This however necessitated adding 0001-sysconfig.py-use-platlibdir-also-for-purelib.patch
to avoid hardcoding 'lib' on target builds as libdir.

Drop chunk from 0001-distutils-sysconfig-append-STAGING_LIBDIR-python-sys.patch as
upstream now uses sysconfig directly inside distutils.

Add 0001-Lib-pty.py-handle-stdin-I-O-errors-same-way-as-maste.patch and
0001-multiprocessing-disable-a-failing-test.patch to address ptest failures.
