All of these suppression prevent the detection of many common mistakes,
and could easily prevent things like T231488. Especially if there are
few issues of a given type, it's way better to suppress them inline,
instead of disabling them for the whole core.
This patch only touches the one with a lower count (although those
counts may be out of date).
Bug: T231636

Most of these are simply changing annotations to reflect
reality. If a function can return false to indicate failure
the @return should indicate it.
Some are fixing preg_match calls, preg match returns 1, 0 or false,
but the functions all claim to return booleans.
This is far from all the incorrect return types in mediawiki, there
are around 250 detected by phan, but have to start somewhere.
