Benchdnn brgemm validation enablement on aarch64

[Shreyas-fuj]

Description

This PR contains enablement of benchdnn brgemm validation for aarch64(Previously it was available only for x86).

Major code changes:
In the following files the namespace has been modified to automatically select aarch64/x64 based on the cpu:

1. oneDNN/tests/benchdnn/brgemm/bench_brgemm.cpp
2. oneDNN/tests/benchdnn/brgemm/brgemm.cpp
3. oneDNN/tests/benchdnn/brgemm/brgemm.hpp
4. oneDNN/tests/benchdnn/brgemm/ref_brgemm.cpp

General

• [yes] Do all unit and benchdnn tests (make test and make test_benchdnn_*) pass locally for each commit?

1. make test

98% tests passed, 3 tests failed out of 164
