Bartosz Dziewoński c03cb71796 Use real type hints for services etc. in api/ApiQuery*.php
Mostly used find-and-replace:

Find:
/\*[\*\s]+@var (I?[A-Z](\w+)(?:Interface)?)[\s\*]+/\s*(private|protected|public) (\$[a-z]\w+;\n)((?=\s*/\*[\*\s]+@var (I?[A-Z](\w+)(?:Interface)?))\n|)
Replace with:
\3 \1 \4

Followed by some manual review to make sure I'm not changing too much,
omitting some changes that looked too complicated and anything that
caused test failures, and some whitespace fixes.
