[libc++] Use [[clang::no_specializations]] to diagnose invalid user specializations (#118167)

Browse Source 
Some templates in the standard library are illegal to specialize for users
(even if the specialization contains user-defined types). The [[clang::no_specializations]]
attribute allows marking such base templates so that the compiler will
diagnose if users try adding a specialization.
