Turn on Compute library testing in CI for AArch64 (apache#8291)

* Turn on Compute library testing in CI.

This pull request turns on compute library testing in CI by

1. Handling import errors in Compute Library Integration.
2. Setting the configuration to the right path for ACL.

This handles import errors for packages in Compute library integration.
This pull request allows for the AArch64 CI to pick up native
compute library testing and tests the operators being offloaded at
runtime.

* Fix typo

* Fix up use of ubuntu_install_arm_compute_lib.sh in Dockerfile.ci_arm

* Move to using pre-built ACL binaries for ci_arm
* Fixup the path for installation to be /opt/acl as it originally was.
* Fix up the issues with paths.

Once this is done ci_arm will need to be rebuilt though will continue
to work seamlessly.
