- Avoid redundant calls to `GetArena()`.
- Only do a single call to `xxx_clear()` if needed.
- Set the oneof_case once, if needed.
- Use CopyConstruct for new objects, like we do for non-oneof Merge.
- Avoid the _Internal::mutable_xxx functions, as they are not needed anymore.

This change names the lifetime of Mut<'a, T> and requires that T outlives 'a. The motivation for this change came up while implementing `Map<K, ProtoStr>`. The Map implementation makes it so that `V` needs to implement the `MapWithKeyOps` trait which has an associated type with a lifetime (`Value<'a>`. The lifetime bound on `T` ensures that e.g. for `MapWithKeyOps<Value<'b>=&'b ProtoStr>` `'a` outlives `'b`.

There is no canonical rules_ruby repo today, and we don't want our fork to become one. In order to unblock inclusion of Protobuf in the bzlmod registry, we're making this a dev dependency and dropping support for Bazel/Ruby.
Fixes#14569

- Inline the once_flag object. This avoids an unnecessary indirection and secondary object.
- Reorganize the fields to reduce the size by 8 bytes.

This change implements the Proxied trait for the Map type.
It leaves a TODO to implement SettableValue. I haven't implemented SettableValue yet because I have not yet been able to verify that we get the right copy_from semantics for both kernels. I'll implement set_on in a follow up.

EXPECT_DEBUG_DEATH runs the statement without expecting a death in NDEBUG mode, causing a test failure in asan due to reaching `__builtin_unreachable`.
Also, improve a bit the definition of Unreachable to be more readable/useful.

This allows for better code generation in C++20 for algorithms that take advantage of random access vs contiguous data.
