QWebEngineClientHints::fullVersionList changes the order of the versions

Using a QVariantMap forces the brand version list to be sorted alphabetically by brand name.

However

1. Accord to the specs, the order should be randomized (https://wicg.github.io/ua-client-hints/#create-ua-list-section)
2. Other chromium browsers do not seem to randomize, but seem to always follow the order: "Not a brand", "Actual brand" and "Chromium"

With the current API is is not possible to follow the specs,  nor to behave like other browsers.
