More binary builds v2 (#582)

* More binary builds v2

* fix version

* fix archs

* lets see what happens

* fix cd script

* typo

* wut

* ok, need true platform

* comment and fix

* fix builds

* more fix

* better test

* fix test

* fix win

* try again

* safer

* add pushd

* cannot install deps with no-index

* maybe like this

* had an extta popd

* sod it

* comments

* try windows test

+# Note that a lot of the cibuildwheel config is in pyproject.toml.
+#
+# We perform one build for each wheel that we generate, i.e. one per architecture.
+# In download_wgpu_native.py, we detect CIBW_PLATFORM and CIBW_ARCHS to determine
+# the required binary from wgpu-native.
+#
+# If https://github.com/pypa/cibuildwheel/issues/944 gets implemented, we can build more wheels per build.
+#
+# Also includes the sdist build that does not include a binary.
