The instructions for `format` failures still referred to using `activate`, which is no longer how tools are invoked. Replace the specific instructions with a link to the relevant README section to make them evergreen.

Makes Objective-C a supported language for macOS in Pigeon, and adds integration tests for it.

Also adjusts CI to only run the macOS version of the integration tests, as is already the case for Swift, since there's less complexity in running macOS integration tests than Obj-C integration tests, and the tests are identical. (As with Swift, we can easily revisit that if we ever find that we miss a bug due to this.)

Fixes flutter/flutter#124724

#4201)

�Route.

fixes flutter/flutter#111678
fixes flutter/flutter#128793

Adds a new Linux_android configuration, and an initial test (build-all-packages) using it.

This is the simplest Android test since it doesn't actually run anything, so starting with this one as a foundation to test future web-based tests.
