test_ios → ✅: Update iOS Snapshots, remove tvOS tests, disable failing tests (facebook#22720)

Summary:
The following tests are disabled in this PR:

- testTimersTest is failing due to undefined this.setTimeout, probably introduced back in 61346d3. Tracking a fix in facebook#22695
- testTheTester_ExpectError is failing as RCTTestRunner is not properly passing through the error. Tracking a fix in facebook#22697

I've added a comment regarding testWebSocketTest and how to ensure it passes locally.

This PR also fixes all remaining snapshot tests, which were failing due to the use of iPhone XS as a iOS Simulator on Circle CI. We are using iPhone 6s for SST internally, and this allows us to be consistent.
