fix(el3_runtime): correct CASSERT for pauth

clang build breaks when both ENABLE_PAUTH (BRANCH_PROTECTOR=1)
and CRASH_REPORTING (DEBUG=1) options are enabled:

include/lib/el3_runtime/cpu_data.h:135:2: error: redefinition of typedef
'assert_cpu_data_crash_stack_offset_mismatch' is a C11 feature [-Werror,
-Wtypedef-redefinition]
        assert_cpu_data_crash_stack_offset_mismatch);
        ^
include/lib/el3_runtime/cpu_data.h:128:2: note: previous definition is here
        assert_cpu_data_crash_stack_offset_mismatch);
        ^
1 error generated.
