Merge pull request #5601 from WoltLab/checkMemoryLimit-float

Accept `float`s in FileUtil::checkMemoryLimit()

Make use of `ini_parse_quantity()` in FileUtil::getMemoryLimit()

If `ini_parse_quantity()` is available (PHP 8.2+) it will certainly be more
accurate and simpler than our home-grown calculator.

Accept `float`s in FileUtil::checkMemoryLimit()

While a decimal amount of bytes is not something that exists, it's a common
pattern to approximate the required memory usage of an image operation with the
factor `2.1`, possibly resulting in decimal places. PHP 8.1 emits a warning if
an implicit cast from non-integer float to int happens.

As the input is only used within an inequality expression and not further
processed it is safe to accept arbitrary floats and preferable to slapping
explicit casts onto everything.
