web: Avoid `copyToChannel` on Safari
...
`AudioBuffer.copyToChannel` does not work on Safari, so switch to
using `getChannelData` to fill the audio buffers.
Limitations in wasm-bindgen prevent us from actually modifying the
data returned by `getChannelData` on the Rust side, so import a JS
function to fill the audio buffer (js-src/ruffle-imports.js).

Calling uncallable values does not actually cause a runtime error in Flash; it just returns null.
...
This was discovered almost by accident: @Dinnerbone noticed that `_global == null`, and surmised that `valueOf` was the culprit. However, this doesn't really make sense: `_global` is a bare object, so it shouldn't have a `valueOf` (and in practice, it doesn't).
The ultimate cause of such an odd comparison is as such:
1. Flash coerces the `_global` object to a numerical primitive by calling `valueOf`.
2. `_global.valueOf` is undefined. Flash handles calls to any uncallable value by literally just having it return `undefined`. In other words, all values are implicitly callable as empty functions.
3. `undefined` is then compared to `null`. These two values *are* equal under abstract equality (`==`). Hence, `_global == null`.
For comparison, modern ECMAScript engines throw errors on calls to uncallable values; and won't attempt to use an invalid `valueOf` to coerce objects. So none of this applies to, say, standard JavaScript in your browser.

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`)

Implement prototype chain recursion limit of 255 prototypes.
...
In Flash, this also at least claims to halt ActionScript execution on the movie. No such implementation of AVM poisoning currently exists in Ruffle, primarily because it's unclear what gets poisoned and implementing some of these options isn't yet possible:
1. AVM (e.g. all movies) - we would need to make the AVM fail silently in this case. This is the most straightforward way to poison the movie, but I'm not sure if this is how Flash actually does it, or if it poisons...
2. Movie - the current structure of movies is incompatible with adding arbitrary data to them. We need to merge `moviefetch` in before we can attach data to loaded movies.
3. MovieClip - this would also be implementable but has problems. How do child MovieClips know that their parent has been poisoned, or vice versa? What if a movie clip is loaded from one movie and moved into another?
As a result, I have decided to hold off on implementing recursion poisoning until I know where it's supposed to go and how to implement that.
