Launching latest Firefox fails due to lack of ARCH_SET_GS support

### Description

On Firefox version 136.0.2, Firefox fails to start up with a failed WebAssembly call:

```
wasm_rt_syscall_set_segue_base error: Invalid argument
Redirecting call to abort() to mozalloc_abort
```

On version 135.0.1, it starts up as expected.

If we `strace` the Firefox call on 136.0.2, we can see that it's failing when trying to use `ARCH_SET_GS`:

```
arch_prctl(ARCH_SET_GS, 0x7ee300000000) = -1 EINVAL (Invalid argument)
```

This limitation is documented:
https://gvisor.dev/docs/user_guide/compatibility/linux/amd64/

We're wondering if implementing `ARCH_SET_GS` is on the near-term roadmap and what the path to implementation would be.

### Steps to reproduce

You can use `runsc` with Docker to repro this. You can change the FF_VERSION parameter to switch behavior:

```
docker run -it --runtime=runsc --rm ubuntu:22.04 /bin/bash

$ apt update && apt install curl -y
$ # export FF_VERSION=135.0.1
$ export FF_VERSION=136.0.2
$ DEBIAN_FRONTEND=noninteractive; (apt-get update && apt-get install --yes --no-install-recommends libasound2 libgtk-3-0 libx11-xcb1 xz-utils) | wc -l
$ curl -sk http://download-installer.cdn.mozilla.net/pub/firefox/releases/$FF_VERSION/linux-x86_64/en-US/firefox-$FF_VERSION.tar.xz | tar -xJv -C /opt | wc -l
$ /opt/firefox/firefox --headless --marionette
