Add iOS Validate Environment Script (#19750) Summary: Fixes #19694 this diff adds an iOS environment validation script as requested by hramos. A similar script for Android exists: scripts/validate-android-test-env.sh. This script: - Validates that the minimum required Xcode version is installed (people using Xcode 8 with a recent release may encounter cryptic build errors). - Validates the correct Node version is installed (Node 10 is not fully supported at the time, Node 6 is no longer supported). <!-- Required: Write your motivation here. If this PR fixes an issue, type "Fixes #issueNumber" to automatically close the issue when the PR is merged. --> Run ./scripts/validate-ios-test-env.sh on a properly setup OSX machine and verify it works, change the version comparison and make sure it fails. <!-- Required: Write your test plan here. If you changed any code, please provide us with clear instructions on how you verified your changes work. Bonus points for screenshots and videos! --> <!-- Does this PR require a documentation change?
