Downgrade Xcode from the default (15.0) to 14.3.1.

This seems to fix two sporadic errors that have been appearing in CI.
One is an issue with cmake being unable to verify that cmake is able to
build a simple test program. The other is a `invalid r_symbolnum`
linking error when trying to build one of cranelift's tests.

This is intended as a temporary fix until we can figure out how to
resolve those issues.
