`ply`, [by design](https://github.com/dabeaz/ply/issues/79), does not produce reproducible table files; hence bug 1633156. (Note that this was *always* true, but only became a problem once we switched to Python 3, which has more unpredictable dict iteration order than Python 2.7, at least prior to [3.7](https://docs.python.org/3/whatsnew/3.7.html#summary-release-highlights).)
In any other circumstance I would consider submitting a patch to `ply` to fix this, but as of the [in-progress version 4.0 of the library](https://github.com/dabeaz/ply/blob/master/CHANGES), it doesn't even emit this cached data any more, and indeed the [latest version of the code](1fac9fed64/ply) doesn't even call `open()` at all except to do logging or to read the text data to be parsed from `stdin`. So if we were going to pin our future on `ply` and upgrade to later versions of the library in the future, we would have to live in a world where `ply` doesn't generate cached table files for us anyway.
Emitting the cached table files so later build steps can consume them is an "optimization", but it's not clear exactly how much actual value that optimization provides overall. Quoth the `CHANGES` file from that repository:
```
PLY no longer writes cached table files. Honestly, the use of
the cached files made more sense when I was developing PLY on
my 200Mhz PC in 2001. It's not as much as an issue now. For small
to medium sized grammars, PLY should be almost instantaneous.
```
In practice, I have found this to be true; namely, `./mach build pre-export export` takes just about as long on my machine after this patch as it did before, and in a try push I performed, there's no noticeable performance regression from applying this patch. In local testing I also found that generating the LALR tables in calls to `yacc()` takes about 0.01s on my machine generally, and we generate these tables a couple dozen times total over the course of the `export` tier now. This isn't *nothing*, but in my opinion it's also not nearly long enough where it would be a concern given how long `export` already takes.
That `CHANGES` file also stresses that if caching this data is important, we have the option of doing so via `pickle`. If and when we decide that re-enabling this optimization is valuable for us, we should take control of this process and perform the generation in such a way that we can guarantee reproducibility.

This rule is based on the ESLint built-in no-throw-literal. Cr.ERRORs are also
literals since they are just integers and so have all the same disadvantages of
no stack info.
TestInterfaceJS.js is explicitly testing handling of throwing raw Cr.ERRORs and
thus needs to stay.

Instead of manually defining toStringTag we now add the toStringTag symbol to the list of properties.
This is also how we usually define toStringTag in the JS engine.
Even though this changes more code I like this approach better. Everything is centralized in the generated bindings file.

This also allows us to remove JSID_FROM_BITS and gives us stronger assertions everywhere for the whack integer-string case.

I am honstely still not convinced that this function should actually exists.
It seems like a convulted way of saying AtomToId, while also asserting that the atom is pinned.

So that we can update the holders table correctly we will need to remove the wrapper from its original vector and add it to the one associated with the new zone.
I tried to make SetPreservingWrapper private but there's still a use in layout/style/Rule.cpp that I couldn't see an obvious fix for.

Implement DOM interfaces for the WebXR Core Module. Additional work to implement the WebXR Core Module are marked with TODO (Bug #) comments within the patch and must be landed before enabling the dom.vr.webxr.enabled flag.
