[debugger] Add more pretty-printers for Fuchsia.

Adds pretty-printers for reference counted types. Previously a
fbl::RefPtr<Foo> with Foo having one "value" would print as:

  {
    ptr_ = (*)0x661538a5d1f0 ➔ {
      fbl::RefCounted<Foo, true> = {
        fbl::internal::RefCountedBase<true> = {
          kPreAdoptSentinel = 1
          ref_count_ = {
            std::__2::__atomic_base<int, true> = {
              std::__2::__atomic_base<int, false> = {
                __a_ = {std::__2::__cxx_atomic_ba… = {__a_value = 1}}
                is_always_lock_free = true
              }
            }
          }
        }
      }
      value_ = 22
    }
  }

and now it prints as:

  (*)0x661538a5d1f0 ➔ {
    fbl::RefCounted<Foo, true> = {ref_count_ = 1}
    value_ = 22
  }

Also adds FBL Span and Vector printers.

Fuchsia

Pink + Purple == Fuchsia (a new operating system)

What is Fuchsia?

Fuchsia is a modular, capability-based operating system. Fuchsia runs on modern 64-bit Intel and ARM processors.

Fuchsia is an open source project with a code of conduct that we expect everyone who interacts with the project to respect.

How can I build and run Fuchsia?

See Getting Started.

Where can I learn more about Fuchsia?
