[Development] supported compilers in 5.10?

[Marc Mutz]

Hi,

Can we drop GCC 4.7 from the list of supported compilers for 5.10? It has a 
bug that makes writing constexpr classes like QSizePolicy, QUuid, ... very 
annoying:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=54922

If we can drop MSVC 2013, too, we can start to use char16_t unconditionlly, 
which will make QStringViewLiteral obsolete, as we can just write u"foo" 
everywhere. It will also simplify a lot of other code that currently needs to 
fall back to wchar_t on Windows / MSVC 2013.

Thanks,
Marc
