azure: use bash scripts across all platforms

Right now, we maintain semantically equivalent build scripts in
both Bash and Powershell to support both Windows and non-Windows
hosts. Azure Pipelines supports Bash on Windows, too, via Git for
Windows, and as such it's not really required to maintain the
Powershell scripts at all.

Remove them to reduce our own maintenance burden.
