Remove deprecated `evalutate_during_training`
# What does this PR do?

Replaces the `evaluate_during_training` in examples using the `Trainer` (as well as integrations and tf_trainer) by the new `evaluation_strategy`.

Fixes #8792
Merging this because we need it for the v4.0.0, pinging @jplu so he's aware of the changes made to the TFTrainer.
