Subject: Allow multiple _AttributeTargets for attribute declaration (#4087)

The syntax like:
[__AttributeUsage(_AttributeTargets.Var)]
[__AttributeUsage(_AttributeTargets.Param)]
struct DefaultValueAttribute
{
    int iParam;
};

is allowed.

For user-defined attribute, we can specify more attribute targets on the
attribute declaration. So one attribute can be used in more than one
situations.
