[2.1]: get_defined_functions_in_file() fails to detect multiline method signatures, marking valid integration hooks as missing

[dragomano]

Basic Information

Some IDEs (e.g., PHPStorm) automatically suggest using a multiline format for long parameters. Therefore, in code you can often find entries like this:

public function modifyBoard(
	int $id,
	array $boardOptions,
	array &$boardUpdates,
	array &$boardUpdateParameters
): void
{
	// Code
}

However, currently SMF only supports the single-line format for such parameters:

public function modifyBoard(int $id, array $boardOptions, array &$boardUpdates, array &$boardUpdateParameters): void
{
	// Code
}

As a result, some hooks are marked as missing, even though they actually exist.

Steps to reproduce

1. Install Optimus 3.0
2. Check the Integration Hooks table in the forum's settings

Recommended fix looks good to me.

Note that this issue most likely also affects SMF 3.0, since both versions use the same regex.
