Update the Windows packaging script

Check in updates based on how the latest release was built [0] and add
the bug fix from [1] which allows LLDB to start.

Other changes which had accumulated in the local release script:
- Don't build the clang format plugin (VS has the functionality built
  in now)
- Disable tests that have been failing (I'll try to follow up and
  re-enable them)
- Switch to Python 3.10
- Jump through more hoops to make LLDB pick the right Python.
