LOG: [compiler-rt][ASan] Define SANITIZER_INTERCEPT_WCSNLEN  (#164845)

Follow up to #162028

`SANITIZER_INTERCEPT_WCSNLEN` is not defined, so `internal_wcsnlen` is
always used instead of using `REAL(wcsnlen)` if intercepted.

Added: 
    

Modified: 
    compiler-rt/lib/sanitizer_common/sanitizer_platform_interceptors.h
