ci: Update the support for cross-build verifications; refactor Rename `CI_HOST_ARCH` and `CI_HOST_SYSTEM`, to `CI_BUILD_ARCH` and `CI_BUILD_SYSTEM`, following the nomenclature used by GNU Autotools. Unfortunately, the word "host" has confusingly opposite meanings in CMake (and Bazel, etc.) vs. Autotools (and Meson, etc.) Remove `CI_TARGET_TRIPLET` and `CI_TARGET_ABI` (for now). Introduce the function `ci_expr` as a fast and easy equivalent of `expr >/dev/null`. Rephrase the assertions using an implementation pattern that is more expressive, yet (arguably) just as readable. Remove `ci_assert`. Modify the main functions to display more useful information in case of usage error.
