Make the CI pass with new clang-tidy

Disable bugprone-suspicious-include since it's triggered by the moc
includes

Disable bugprone-reserved-identifier since it's triggered by all our

reserved, are we going to be that unlucky that the library decides to
start using _OKULAR ? not probably

Add two TODOs for the future to make NormalizedRect/Point faster

Silence a warning about a quick moving QString if we make it non const

Silence a uchar vs char warning that is in decades old code so
experience seems to suggest it's ok.
