BeanValidator should use EL-coerced value as bean property value

[BalusC]

Discovered during https://github.com/eclipse-ee4j/mojarra/issues/5596

• have a Byte property with @Min(1)
• have a <f:convertNumber> (just for formatting)
• but NumberConverter returns Long
• this is usually EL-coerced during update model values phase, so no problem during usual Faces lifecycle
• but this Long is passed to BeanValidator#validateValue() during validations phase
• Hibernate Validator errors out with ClassCastException on Long -> Byte

This seems to have uncovered a potential bug in BeanValidator.

The BeanValidator#validate spec needs to be updated from

 * <p>
 * Obtain a <code>jakarta.validation.BeanDescriptor</code> from the <code>jakarta.validation.Validator</code>. If
 * <code>hasConstraints()</code> on the <code>BeanDescriptor</code> returns false, take no action and return. Otherwise
 * proceed.
 * </p>
 *
 * <p>
 * Call {@link jakarta.validation.Validator#validateValue}, passing <em>valueBaseClass</em>, <em>valueProperty</em>, the
 * <em>value</em> argument, and <em>validatorGroupsArray</em> as arguments.
 * </p>
