Fixes #5065 and fixes #5066.

NOTE: This PR touches only Bazel files (*.bzl, *.bazel, bazel/**).

This currently requires one temporary ugliness since P4Runtime has not yet been added to the Bazel Central Registry (p4lang/p4runtime#572).

Acknowledgements: Google Antigravity/Gemini 3 did most of the heavy lifting on this PR. I reviewed, refined some details, and provided guidance.

Add p4c 1.2.5.11 (#7761)
f332008 
## Description

Adds [p4c](https://github.com/p4lang/p4c) v1.2.5.11 — the P4_16
reference compiler — to the BCR. This is the first p4c submission, made
possible by the Bzlmod migration completed in this release
([p4lang/p4c#5454](p4lang/p4c#5454),
[p4lang/p4c#5497](p4lang/p4c#5497)).

## Module
- **Name:** `p4c`
- **Version:** `1.2.5.11`
- **Source:** https://github.com/p4lang/p4c/releases/tag/v1.2.5.11

## Notes

- The `inja` dependency is not yet in the BCR and is loaded via a module
extension defined in p4c's own `bazel/repositories.bzl`. This is
self-contained and requires no BCR changes.
- The `p4c_ir_extensions` module extension provides an opt-in mechanism
for downstream users to register custom IR extensions; it has no effect
unless explicitly used.
- Presubmit builds `@p4c//...` on Ubuntu 22.04 and 24.04 against Bazel
7.x, 8.x, and 9.x.

## Checklist

- [x] Module added under `modules/p4c/`
- [x] `metadata.json` with homepage, maintainers, and repository
- [x] `source.json` pointing to the release tarball with verified
SHA-256 integrity
- [x] `MODULE.bazel` with correct version
- [x] `presubmit.yml` covering Ubuntu 22.04/24.04 × Bazel 7/8/9
