hwasan: Check if Intel LAM_U57 is enabled

When -fsanitize=hwaddress is used, libhwasan will try to enable LAM_U57
in the startup code.  Update the target check to enable hwaddress tests
if LAM_U57 is enabled.  Also compile hwaddress tests with -mlam=u57 on
x86-64 since hwasan requires LAM_U57 on x86-64.

* lib/hwasan-dg.exp (check_effective_target_hwaddress_exec):
Return 1 if Intel LAM_U57 is enabled.
(hwasan_init): Add -mlam=u57 on x86-64.
