subsys/testsuite/ztest: change zassert_mem_equal to macro

Browse source 
This commit changes zassert_mem_equal as a macro instead
of a function implementation.
In the previous implementation when an assertion fails
the location inside ztest_assert.h file was displayed.
This modification displays the location where zassert_mem_equal
was used.
