This removes aarch64 specific code branches for caching oneDNN matmul primitive in ideep.
Instead, we rely on primitive caching in oneDNN. Since oneDNN v3.6 matmul primitive with ACL
backend leverages the experimental stateless API in ACL and thus can be cached more efficiently.
The work to make ACL lowp matmul primitive is still in progress. Please hold off merging this PR
until that work is done.
