Note: This work is continued from a PR started under the WordPress GH org. There are a couple of reasons for this upgrade: 1. I am having trouble rebuilding php-wasm on my current system. References to older ubuntu images and emscripten versions [has given me trouble](#2038 (comment)). 2. We want [this Emscripten fix](emscripten-core/emscripten#22932) from @jeroenpf and @bgrgicak which was first included in Emscripten 3.1.73. This PR: - Bumps the ubuntu docker image version due to build errors related to missing image. Referencing a newer ubuntu image seemed to fix the "missing image" errors. - Bumps Emscripten version - Adjusts Playground-specific patches to Emscripten output since the latest breaks that patching. - CI (once we can run GH actions on A8C's GHE instance) --------- Co-authored-by: Brandon Payton <brandon@happycode.net>
The original implementation of the DNS polyfill didn't register `DNS_*` constants which are [expected to exist in PHP](https://www.php.net/manual/en/network.constants.php#constant.dns-any). To fix this this PR registered the required DNS constants. The constants were already defined in the polyfill and now we register them as PH constants using `REGISTER_LONG_CONSTANT`. I didn't want to add more code to the `php_wasm.c` file that wasn't directly related to PHP-wasm, so I moved the DNS polyfill code to an extension. - CI

Let's wait for CI tests to pass. And before merging, I would like to temporarily allow merging discrete commits from PRs in order to keep the two commits separate on trunk. The change should only remain for a moment so we can merge. |

@brandonpayton I looked into the CI failures and they're all benign:
We should be able to backport the related fixes here realtively easily, but we also don't have to hold up this PR because of those failures. |
