ec: Make it possible to run tests with AddressSanitizer enabled
Automatically use CC=clang if TEST_ASAN is specified.
Also, add a __no_sanitize_address attribute macro to prevent ASan
from adding guards around host_command, mkbp_event, and hook
"arrays" that are generated at link-time.
Also, set ASAN_OPTIONS env variable in run_host_test.
BRANCH=none
BUG=chromium:854924
TEST=make TEST_ASAN=y runtests -j
