Bug 1621252 - Move Fenix Raptor tests to tier 1

[liuche]

Pushing this from #9197 to run CI - though I don't think this will run the Raptor CI, will it @JohanLorenzo ? I guess we'll see!

I think we are OK here
Decision Task Successful in 1m — FirefoxCI (pull_request)

Last time Decision Task was failing with:

Exception: raptor-tp6m-13-cold-performance-test-armeabi-v7a (tier 1) cannot depend on signing-performance-test (tier 2)

it would be nice to have the power to trigger a actual raptor test

Hey @bebef1987!

I have some great news! @tomprince recently enabled a feature. I tested it last week and it worked great. I'm going to document this, but in the meantime, you can just create a file called try_task_config.json in the main folder. Commit/push it and you will be able to trigger an actual raptor test.

Here's what the file should contain:

{
    "parameters": {
        "optimize_target_tasks": true,
        "target_tasks_method": "raptor"
    },
    "version": 2
}

@JohanLorenzo I don't have the power to trigger these builds that's why @liuche had to make a copy of my pull request...

[JohanLorenzo]

@bebef1987 Oh my apologies! I hadn't realized you didn't. I just pushed the change I mentioned. Here's what will happen once your PR is merged. I see the decision task is green, so this PR is in good shape.

By the way, I'm sorry I didn't catch the bug in the original PR. I had forgotten taskgraph was super strict with tiers.

I'm going to push a backout of my commit once tests are green :)
