Add iOS Validate Environment Script (#19750)

Harry Tormey · facebook-github-bot · commit 1fb7a25f7b96 · 2018-08-01T20:46:58.000-07:00
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).  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.
