Summary:
Change the `TransactionTelemetryTest` to use a mock clock or change the tests to only test if at least x amount of time has passed.
Using a mock clock is the only way to make the test deterministic and be able to assert on the sub-results of the captured phases.
Changelog: [Internal] Change to the `TelemetryTest`. Neither changes the runtime behavior nor the API.

Summary:
The current test failures don't include the values passed to `EXPECT` which makes it difficult to understand if the test ended earlier or later then expected.
```
Failure: Value of: (commitDuration >= 1000 - threshold) && (commitDuration <= 1000 + threshold)
Actual: false
Expected: true
```
This diff uses the gtest `EXPECT_NEAR` to get exception messages including the delta:
```
Failure: The difference between telemetryDurationToMilliseconds(telemetry.getTextMeasureTime()) and 600 is 153, which exceeds threshold, where
telemetryDurationToMilliseconds(telemetry.getTextMeasureTime()) evaluates to 753,
600 evaluates to 600, and
threshold evaluates to 70.
```
This doesn't change the test's flakiness because of how sleep is implemented.

Summary:
We need to do this to break a dependency cycle that would happen if we try to have `view` depend on `mounting` just to add some telemetry to `view`.
Changelog: [Internal] Fabric-specific internal change.
