Subject: [PATCH] Check if cmake is installed on RNTester (#39208)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/39208

To properly build RNTester for iOS, we need cmake installed.
This small change check whether Cmake is present in the system. If not, it tries to install it using `brew` if that's available.
Otherwise, it exits with an error message asking to install cmake.

## Changelog:
[Internal] -  Check whether Cmake is present for RNTester
