Squiz/MultiLineFunctionDeclaration: bug fix - skip over attributes

The sniff looks for `T_COMMA` tokens to find the start of the next parameter and skips over parenthesis sets and square brackets sets (like short arrays) to prevent mismatching on a `T_COMMA` which is not a parameter separator.

This logic did not take parameter attributes into account, which can contain multiple comma-separated attributes, so should also be skipped over.

Fixed now. Includes plenty of tests.

Also includes minor stability fix for the parentheses/square brackets skipping.

Notes:
* It could be argued that the sniff should use the `File::getMethodParameters()` method to do the parameter parsing instead. This could be done in a future iteration, but will need to be evaluated carefully for side-effects.
* This sniff extends the PEAR `FunctionDeclaration` sniff. It has been verified that that sniff is not affected by this bug.
