  [cross-project-tests] Avoid requiring packaging for GDB/LLDB version checks

Previously, `cross-project-tests/lit.cfg.py` imported `packaging.version` to
compare GDB and LLDB version numbers and unconditionally called
`lit_config.fatal()` when the third-party `packaging` Python package was not
installed in the test environment. Try `packaging.version.parse` first, fall
back to splitting dot-separated integer components when `packaging` is not
available, and raise `ValueError` on unparseable versions so each caller can
emit a context-specific warning instead of aborting the test suite.
