QSysInfo: don't pass QStringLiteral to QWinRegistryKey::stringValue()
The stringValue() function took QStringView from the initial commit of
the class, so passing QStringLiteral (which creates and destroys a
full QString instance, and, until recently, even injected an
additional isNull() branch when converted to QStringView) was never
necessary; a UTF-16 string literal would have always sufficed, and be
faster.
Since the API will will soon be changed to take const wchar_t*, use a
wchar_t literal instead of char16_t one. For QStringView, it doesn't
matter (on Windows, at least), but it keeps the call compatible with
the future QWinRegistryKey API.
Amends 80996d2e5d6d04b08452cf507f6ced7d8a09068c.
Pick-to: 6.10 6.8 6.5
