Replace qExchange with std::exchange

None of these users require C++20 constexpr or C++23 noexcept, the
only remaining difference between std::exchange and qExchange.

This leaves a single qExchange() user, in QScopedValueRollback, that
requires the constexpr version, only available from C++20, and thus
remains unported.
