Make Bazel clearly communicate issues with XCode install

I updated the OS but did not update XCode. Bazel was failing with the most cryptic error (see below).

Please make Bazel messaging more helpful, possibly suggesting the user to check XCode install and do bazel clean --expunge

Description of the bug:

Unable to build my branch on my local macOS environment. This branch builds on CI, including Mac.

FATAL: bazel crashed due to an internal error. Printing stack trace:
