Windows: add script to build a .msi package

Also add a test, though there's no build rule to
wrap it yet.

The generated installer:
- is a standard .msi installer that users are
  familiar with
- installs Bazel at a short and safe path (no
  space in path)
- updates the PATH envvar
- handles uninstall, upgrading, parallel installs:
  backwards-compatible versions can be upgraded
  (but not downgraded), while incompatible
  versions may be installed side by side
  (see `guids.txt` comments)

Example use:

```
c:\src\bazel>powershell scripts\packages\msi\make_msi.ps1 ..\bazel-releases\0.26.1\bazel-0.26.1-windows-x86_64.exe
(...)
INFO[make_msi_lib.ps1 11:41:33] Creating wixobj
INFO[make_msi_lib.ps1 11:41:33] Creating msi
INFO[make_msi_lib.ps1 11:41:42] Done: ..\bazel-releases\0.26.1\bazel-0.26.1-windows-x86_64.msi

c:\src\bazel>start ..\bazel-releases\0.26.1\bazel-0.26.1-windows-x86_64.msi
```

TODO(@laszlocsomor) before we can use this:
- figure out if we should bundle vc_redist with
  the Bazel installer
- figure out the UpgradeCode for such a combined
  bundle

Closes #8579.
