[roll] Roll fuchsia [display][api-types-cpp] Rework AlphaMode.

This CL updates AlphaMode to be its own type (as opposed to an alias for
a FIDL type), so driver code is guaranteed to use IsValid() and ToFidl()
/ ToBanjo(). The update gives AlphaMode constexpr conversion methods, so
it can be used in higher-level types that offer constexpr conversion
to/from FIDL/Banjo.

This CL also calls out that we haven't updated the AlphaMode interface
for API stabilization, so it's not suitable for OOT drivers.
