ci: explicitly disable CRLF conversion on Windows

The Azure image enables CRLF conversion on Windows builders, but that caused regressions both in our test suite (the miri test suite broke) and in the ecosystem, since we started shipping install scripts with CRLF endings instead of the old LF. The [Godbolt Compiler Explorer](https://godbolt.org/) is one such case of breakage.

This adds a step to the build explicitly disabling the conversion before the repository is checked out.
