Remove the wasmtime Python extension from this repo (#1457)

* Remove the wasmtime Python extension from this repo

This commit removes the `crates/misc/py` folder and all associated
doo-dads like CI. This module has been rewritten to use the C API
natively and now lives at
https://github.com/bytecodealliance/wasmtime-py as discussed on #1390
