Some headers cannot be sent via XMLHttpRequest. In case one of those is
assigned to a network request, the header will now be trimmed on WASM so
that the request continues. Qt will print a warning on each request that
had its headers trimmed.
The list seems stable so it is not a lot of burden to sync Qt with it on
potential (unlikely) changes.
