QVarLengthArray: fix aliasing error in insert(it, n, v)
Taking the copy after the resize is completely pointless: the copy is
there to ensure that `t`, being a reference potentially aliasing an
element in [begin(), end()[ before the resize(), isn't invalidated by
the resize(), so it must be taken before resize().
Add a comment so the next rewrite doesn't cause this to be mixed up
again.
[ChangeLog][QtCore][QVarLengthArray] Fixed an aliasing bug affecting
insertions of objects aliasing existing elements.
Pick-to: 6.2 6.1 6.0 5.15 5.12
