Make `JsSymbol` thread-safe (#2539)
The section about `Symbol` on the [specification](https://tc39.es/ecma262/#sec-ecmascript-language-types-symbol-type) says:
> The Symbol type is the set of all non-String values that may be used as the key of an Object property ([6.1.7](https://tc39.es/ecma262/#sec-object-type)).
Each possible Symbol value is unique and immutable.
Our previous implementation of `JsSymbol` used `Rc` and a thread local `Cell<usize>`. However, this meant that two different symbols in two different threads could share the same hash, making symbols not unique.
Also, the [GlobalSymbolRegistry](https://tc39.es/ecma262/#table-globalsymbolregistry-record-fields) is meant to be shared by all realms, including realms that are not in the same thread as the main one; this forces us to replace our current thread local global symbol registry with a thread-safe one that uses `DashMap` for concurrent access. However, the global symbol registry uses `JsString`s as keys and values, which forces us to either use `Vec<u16>` instead (wasteful and needs to allocate to convert to `JsString` on each access) or make `JsString` thread-safe with an atomic counter. For this reason, I implemented the second option.
This PR changes the following:
- Makes `JsSymbol` thread-safe by using Arc instead of Rc, and making `SYMBOL_HASH_COUNT` an `AtomicU64`.
- ~~Makes `JsString` thread-safe by using `AtomicUsize` instead of `Cell<usize>` for its ref count.~~ EDIT: Talked with @jasonwilliams and we decided to use `Box<[u16]>` for the global registry instead, because this won't penalize common usage of `JsString`, which is used a LOT more than `JsSymbol`.
- Makes the `GLOBAL_SYMBOL_REGISTRY` truly global, using `DashMap` as our global map that is shared by all threads.
- Replaces some thread locals with thread-safe alternatives, such as static arrays and static indices.
- Various improvements to all related code for this.
