QLatin1String: add at()/op[]/mid()/right()/left()

QLatin1String can be used as a string-view-like type.
When attempting to do so in uic, mid() and at() were
found to be missing. Added the others for completeness.

Use the new functions in uic, for which they were
originally conceived.

[ChangeLog][QtCore][QLatin1String] Added at(),
operator[](), mid(), right(), left().
