This should be _relatively_ easy. `_statistics` needs to be defined as a built-in module and `_normal_dist_inv_cdf` should be added as its sole function. `_normal_dist_inv_cdf` is pretty straight-forward to implement with the [C version](https://github.com/python/cpython/blob/main/Modules/_statisticsmodule.c#L29) being a pretty direct translation from the [Python version](https://github.com/RustPython/RustPython/blob/main/Lib/statistics.py#L825).
