PR #76831: aarch64: set compute library openmp runtime to off by default

Imported from GitHub PR tensorflow/tensorflow#76831 since the official wheel binary is using Eigen thread pool runtime, there is no dependency on OpenMP. However, having openmp ON by default in compute library bazel config causing an unnecessary dependency on `libgomp/libomp` for aarch64 linux wheel. This PR is to remove the dependency.
