Add datawire-envoy (#29400)

This is a fork of envoy with patches applied by Ambassador for their
emissary project.
See
https://github.com/emissary-ingress/emissary/blob/ac2dc64c6621cd8ec5617f3328544364bdd3fb01/DevDocumentation/ARCHITECTURE.md#envoy

The only modification here from base envoy is the source location. These
should try and stay in sync, but I don't know if there's a better way to
represent this.

### Pre-review Checklist

<!--
This checklist is mostly useful as a reminder of small things that can
easily be
forgotten – it is meant as a helpful tool rather than hoops to jump
through.

At the moment of this PR you have the most information on what all the
change
will affect, so please take the time to jot it down.

Put an `x` in all the items that apply, make notes next to any that
haven't been
addressed, and remove any items that are not relevant to this PR.

-->

#### For new package PRs only
<!-- remove if unrelated -->
- [x] This PR is marked as fixing a pre-existing package request bug
- [ ] Alternatively, the PR is marked as related to a pre-existing
package request bug, such as a dependency
- [ ] REQUIRED - The package is available under an OSI-approved or
FSF-approved license
- [ ] REQUIRED - The version of the package is still receiving security
updates
- [ ] This PR links to the upstream project's support policy (e.g.
`endoflife.date`)

#### For new version streams
<!-- remove if unrelated -->
- [x] The upstream project actually supports multiple concurrent
versions.
- [ ] Any subpackages include the version string in their package name
(e.g. `name: ${{package.name}}-compat`)
- [ ] The package (and subpackages) `provides:` logical unversioned
forms of the package (e.g. `nodejs`, `nodejs-lts`)
- [ ] If non-streamed package names no longer built, open PR to withdraw
them (see [WITHDRAWING
PACKAGES](https://github.com/wolfi-dev/os/blob/main/WITHDRAWING_PACKAGES.md))

I believe this supports the same upstream version streams as envoy.
