A non-friendly error message appears in the logs when trying to create a new user through API with a firstName that is longer than allowed

Issue

Trying to create a new user via API with a longer than allowed firstName produces a non-friendly error message in the logs

Reproducing steps

Start Liferay and go to Control Panel > Server Administration > Script

Use the following Groovy script to create a new user via API with a very long firstName (longer than 75 characters).

import com.liferay.portal.kernel.service.UserLocalServiceUtil;
import com.liferay.portal.kernel.util.LocaleUtil;
import com.liferay.portal.kernel.service.ServiceContext;
import com.liferay.portal.kernel.service.ServiceContextThreadLocal;
import com.liferay.portal.kernel.model.User;

ServiceContext serviceContext = ServiceContextThreadLocal.getServiceContext();
long companyId = serviceContext.getCompanyId();
User defaultUser = UserLocalServiceUtil.getDefaultUser(companyId);
String firstName = "veryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryveryverylongfirstname";

UserLocalServiceUtil.addUser(defaultUser.getUserId(), companyId, false, "1234", "1234", true, null, "user01@liferay.com", 0, null, LocaleUtil.getDefault(), firstName, null, "user01", -1, -1, true, 1, 1, 1977, "", new long[0], new long[0], new long[0], new long[0], false, serviceContext);

Observed Behavior: There's an error in the log produced by the database indicating that one of the fields is too long for the existing constraint (VARCHAR(75)).

Expected Behavior: There's a friendly error message generated by Liferay explaining that the argument firstName is longer than the maximum number of characters allowed.
