Add ThreadSanitizer suppression file

Browse Source 
Using no_sanitize("thread") disables instrumentation for the entire
stack frame, meaning functions called within that scope are also not
checked. By using race_top in a suppression file, we can suppress
erros only when they occur at the top of the stack. This provides more
granular control over errors suppression.
As an example, this suppression addresses #2222.

# This file contains suppressions for Thread Sanitizer.
# For the specification, refer to: https://github.com/google/sanitizers/wiki/threadsanitizersuppressions
# Thread Sanitizer reports data races on Finished and NoDelayFlag in CONNECT_SERIAL_PARAM,
# shared between BindConnectThreadForIPv4, BindConnectThreadForIPv6, and BindConnectEx5.
# These are benign data races: the Set/Wait on FinishEvent provides synchronization
# equivalent to a lock, but TSan cannot recognize it.
