Some messages may contains multi line content, ie snapshot comparison, multiline strings comparison.
Fixing this by checking first code pointer in the stack and slicing from there.

Changelog: [internal]
Right now, when we run individual Fantom tests, we compile Hermes and the RN Tester CLI as part of the test, which causes the first test to run to be very slow and the remaining tests in the same run to be very fast.
This is misleading because it makes it look like the test itself is slow, when it's actually paying a price for everyone.
Fortunately, Jest has an option to do a global setup before any tests in the project run (and it doesn't run if none of the tests in the project run, in multi-project setups), so we can use it to do the necessary warmup so it doesn't end up being attributed to individual tests.

We need more expectations for a new test we're writing. This just adds:
* `expect(received).toBeLessThanOrEqual(expected)`
* `expect(received).toBeGreaterThanOrEqual(expected)`

Pull Request resolved: https://github.com/facebook/react-native/pull/47994
Changelog: [internal]
This adds a few hacks to improve errors messages in Fantom tests. Before, we were only logging the error message. After this, we log the message and the full (unsymbolicated for now) stack, including a pretty print of the exact location of the error.
For errors thrown from `expect` functions, the stack trace is modified to remove the "infra" lines from the stack.
The next step is symbolicating the errors using source maps generated by metro.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/47646
changelog: [internal]
In order to control scheduling of tests, test setup must be separated from test running. This is because of how internal scheduling of React Native is restricted until bundle is loaded via BufferedRuntimeExecutor. This is the reason for executing tests by calling global function `$$RunTests$$`. This is not a pretty solution but it is hidden within testing infrastructure and users of our test infra are not exposed to this.
There is a new method exposed to JavaScript: flushMessageQueue. This will flush everything that is inside of message queue. This is the queue where tasks are queued whenever RuntimeScheduler enqueues something by calling `runtimeExecutor_`.
