Implement ECMAScript compliant type coercions.
...
This includes ECMA-262 2ed `ToNumber`, `ToPrimitive` (Number), `ToString`, and abstract equality and less-than implementations. Note that `ToPrimitive` is only the "number hint" variant, and Flash specifically *never* calls `toString` like how ECMA-262 specifies.
Several builtins inherit numerical coercion - I'm not 100% sure if that's correct.
The following ActionScript opcodes now perform ECMA-262 style coercions:
`ActionAdd2` (uses `valueOf` / "ToPrimitive hint Number")
`ActionDecrement` (uses `valueOf`)
`ActionEquals2` (uses `valueOf`)
`ActionGetMember` (member names, uses `toString`)
`ActionIncrement` (uses `valueOf`)
`ActionLess2` (uses `valueOf`)
`ActionGreater` (uses `valueOf`)
`ActionSetMember` (member names, uses `toString`)
`ActionStringEquals` (uses `toString`)
`ActionStringGreater` (uses `toString`)
`ActionStringLess` (uses `toString`)
`ActionToNumber` (uses `valueOf`)
`ActionToString` (uses `toString`)
`ActionTrace` (uses `toString`)
The following functions now gained user-specified coercions via `toString`:
`_global.number` (uses `valueOf`)
`_global.is_nan` (uses `valueOf`)
Every function in `Math` (uses `valueOf`)

Move `force_set` and `force_set_virtual` into the `Object` trait. They are now called `define_value` and `add_property`, respectively.
...
While I don't expect every host object to implement it correctly, this also gets rid of a lot of unnecessary `unwrap` calls that would allow a poorly-written Flash file to kill the interpreter.

Separate `Object` into an interface trait and a standard implementation. Host object implementations may bypass `ScriptObject` and directly interface with the AVM using this trait.
...
Note that host objects that do so will *not* have access to their standard representation from within member functions - you will need to extend the interface to accomodate for them. This is due to long-standing limitations with type IDs and downcasting with types that bear lifetimes - it's entirely an unsafe operation and exposing such a facility to safe Rust is unsound. However, this will at least let us separate out several things from ScriptObject that don't need to be there for the time being.

Implement explicit prototypes on user-generated functions.
...
`Object::function` now returns a pre-allocated function object. You may supply it an explicit prototype to have it linked into the function object (which is why we have to return a cell).

Replace `Option<Value<'gc>>` with a dedicated `ReturnValue<'gc>` type with associated methods.
...
This type explicitly signals if an immediate value is to be returned, if a value is to be returned on the stack, or if no return value is to be generated. Holders of a `ReturnValue` can also use `and_then` to schedule a `StackContinuation` to be executed when and if that value is ready.
`StackContinuations` now yield `ReturnValues` as well, so they have a moderate level of composability. For example, if you need to get a property from an object and push it on the stack, you can return the result of calling `get` directly and the machinery ensures it eventually gets there.

core: implement isNaN and Number functions. Involves updating to_number function in Value. Note: this varies a little from the ECMA spec such as not allowing spaces in numbers (i.e. ' 5' => NaN). No definitive reference for this but was found experimentally. Same with not supporting 'Infinity'
