[roll] Roll third_party/pigweed pw_ring_buffer: Make iterator entry mutable

Provide a distinction between iterator and const_iterator such that
iterator contains a pw::ByteSpan buffer (mutable data) and
const_iterator contains pw::ConstByteSpan buffer (const data).

Enable copy constructors and stricter iterator equality checks:
- Iterators not pointing to the end must also point to the same data in
  order to be considered equal.
- Const iterators can be copied to other const iterators.
- Const iterators cannot be copied to mutable iterators.
- Mutable iterators can be copied to both mutable and const iterators.
