QStyle: add name() to return the name of the style

Currently there is no way to get the name of the current style to e.g.
create a QProxyStyle for a specific widget only.
Therefore add QStyle::name() so QProxyStyle(const QString &) can be
called without hard-coding the style name.
Remove an unused doc snippet as drive-by.
