uic: use C string literals for setObjectName()

Because setObjectName() now takes a QAnyStringView, passing C string
literals is much more efficient than using QString::fromUtf8().

This patch only deals with setObjectName() as a known property,
probably from a name attribute. If the objectName property is set by a
<property> element (or so I assume), we still emit a
QString::fromUtf8(). Detecting objectName there would be too much
magic.

Besides, I haven't been able to find why sometimes there's a second
setObjectName call right after the first, when in the XML it seems all
kosher (name attribute and objectName <property> agreeing on the
content).
