  [Clang] Deprecate `__is_trivially_relocatable` (#138835)

The C++26 standard relocatable type traits has slightly different
semantics, so we introduced a new
``__builtin_is_cpp_trivially_relocatable`` when implementing trivial
relocation in #127636.

However, having multiple relocatable traits would be confusing in the
long run, so we deprecate the old trait.

As discussed in #127636

`__builtin_is_cpp_trivially_relocatable` should be used instead.
