The chocolatey tool that was fetching us wix v3 can no longer be used to
fetch wix v4+ so we had to switch to dotnet to fetch the latest wix.

This commit builds the installer with wix v5.
wix v5 is installed via the `dotnet` tool in the windows image itself
at containers/automation_images#354.

Going forward, the `dotnet` tool will also be used to build the installer.

In the process, the wix v3 files were converted to wix v4+ using `wix
convert` followed by manual modifications along with switch to wixproj
builds with dotnet.

Contributions from Mario Loriedo:
- bundle setup update to wix5
