[webkit-dev] C++17 is here. Should we use it?

Alex already switched all WebKit ports to building with C++17 enabled 
in https://bugs.webkit.org/show_bug.cgi?id=197131.

We've previously agreed that we can increase the GCC version limit to 
GCC 7, but nobody ever implemented this. Reported 
https://bugs.webkit.org/show_bug.cgi?id=198914.

The easiest way to sniff out which bots should be upgraded is to just 
land the change and see which bots break. But I'll ask internally to 
ensure all remaining Igalia bots are upgraded to GCC 7 soon.

Be aware that while GCC 7 has basic support for structured bindings, 
there are limitations documented at 
https://gcc.gnu.org/projects/cxx-status.html which are not supported 
until GCC 8.
