Description

MinGW builds currently compile the GCS testbench and grpcio for MinGW.
When the compiled MinGW wheel is not in cache, compiling takes a very long time (*). But Win32 and Win64 binary wheels are available on PyPI.

This is pointless: the GCS testbench could simply run with the system Python instead of the msys2 Python, and always use the binaries from PyPI.

(*) see for example https://github.com/pitrou/arrow/runs/8071607360 where installing the GCS testbench took 18 minutes
