Wix ignores product-name specified in package.metadata.wix

When building an MSI installer, we were unable to override the default Product Name, which should be possible by specifying `product-name` in the package's `package.metadata.wix` section.

While investinating the issue we noticed that the wix print builder doesn't actually load certain properties from Cargo.toml but uses a different defaulting strategy instead.

Opened https://github.com/axodotdev/cargo-dist/pull/1798 to address this issue.

Start with the package.metadata.wix settings in Cargo.toml and the Wix print builder, then review PR #1798, which was opened to address this issue. Done means an MSI build uses the configured product-name instead of the default Product Name.
