Mark all side-effectful mysqli_ functions in function metadata 
In response to review feedback: many other mysqli_ functions beyond
mysqli_connect have side effects (network I/O, state mutation, cursor
advancement) and were defaulting to hasSideEffects=maybe. This could
cause the same false positive as phpstan/phpstan#14473 for any of these
functions when used with the `or die()` pattern.

Added 56 additional mysqli_ functions covering connection management,
query execution, transactions, result fetching, cursor positioning,
prepared statements, and administrative operations.
