Clarify whether custom beans need to declare the qualifier "Any"

It's not obvious whether custom beans contributed through a portable extension need to return the Any qualifier from there getQualifier() methods or not (the CDI implementation would be required to add it if missing then).

Concerned spec sections are:

Section 2.3.1:

Every bean has the built-in qualifier @Any, even if it does not explicitly declare this qualifier ...

And section 11.1 which says:

getTypes(), getQualifiers(), getScope(), getName() and getStereotypes()
must return the bean types, qualifiers, scope type, bean name and
stereotypes of the bean, as defined in Chapter 2
