Add reference, pointer, and co type aliases for rtc::ArrayView.

Browse source 
Many STL containers define these type aliases, and they are easier to
work with than add_const_t<add_lvalue_reference_t<value_type>>.

In a followup, `WTF::Vector` in Blink's conversion constructor from
other containers will be SFINAE-guarded using these type aliases.
