Stella Laurenzo cb7b03819a [mlir][python] Simplify python extension loading. ... * Now that packaging has stabilized, removes old mechanisms for loading extensions, preferring direct importing. * Removes _cext_loader.py, _dlloader.py as unnecessary. * Fixes the path where the CAPI dll is written on Windows. This enables that path of least resistance loading behavior to work with no further drama (see: https://bugs.python.org/issue36085). * With this patch, `ninja check-mlir` on Windows with Python bindings works for me, modulo some failures that are actually due to a couple of pre-existing Windows bugs. I think this is the first time the Windows Python bindings have worked upstream. * Downstream changes needed: * If downstreams are using the now removed `load_extension`, `reexport_cext`, etc, then those should be replaced with normal import statements as done in this patch.
