QDeadlineTimer: link to cppreference.com for chrono_literals
Also don't use 'using namespace chrono' in snippets, but spell the
types (nanoseconds, steady_clock) out in full. That doesn't break
line-length limitations and makes it clearer (for the reader, and
eventually, qdoc (when QTBUG-138535 lands) where each identifier comes
from.
Also remove the using namespace std::chrono_literals from the code
snippets. They are repetitive and the linked cppreference.com gives
all the available options how to import them, not just the one chosen
here.
Amends 12eacc3bab00f23d187a295b35e4a0d283ba85f4.
Pick-to: 6.10 6.9 6.8 6.5
Task-number: QTBUG-138538
