fix(install): use test-compile instead of xcrun for Xcode license detection (#4151)

Browse Source 
xcrun --show-sdk-path can succeed even when the Xcode/CLT license has
not been accepted, so the previous check was ineffective. Replace it
with an actual test-compilation of a trivial C file, which reliably
triggers the exit-code-69 failure when the license is pending.
