We have code inside LibWeb that uses the `AK::StringUtils::convert_to_uint`and `AK::StringUtils::convert_to_int` methods for parsing integers. This works well for the most part, but according to the spec, trailing characters are allowed and should be ignored, but this is not how the `StringUtil` methods are implemented. This patch adds two new methods named `parse_integer` and `parse_non_negative_integer` inside the `Web::HTML` namespace that uses `StringUtils` under the hood but adds a bit more logic to make it spec compliant.
