Fix to not miss the entire set of counters to be added in addObject for CounterContext::updateSupportedCount

[judyjoseph]

Fixes issue: sonic-net/sonic-buildimage#21232

In MACSEC there are two set of counters one for INGRESS another for EGRESS which gets mapped to the same COUNTER type - CounterType::MACSEC_SA ( https://github.com/sonic-net/sonic-swss/blob/c20902f3195b5bf8a941045e131aa1b863b69fd0/orchagent/macsecorch.cpp#L2145 )

In the releases after 202205 we started seeing this behavior where the MACSEC RX counters were missing as mentioned in the issue 21232. Further debugging pointed to issue seen after this PR : #1073 was merged.

In this case when macsec orch tries to addCounter for INGRESS SA after the EGRESS SA, and it don't go through as the m_supportedCounters is not empty.

For a fix I am removing the check in CounterContext::updateSupportedCount, which I think is ok as we anyways do a check later on in getSupportedCounters() API using isCounterSupported() before calling collectData()

sonic-sairedis/syncd/FlexCounter.cpp

Line 939 in 1684aec

if (isCounterSupported(counter))

Maybe we can set always_check_supported_counters to true for macsec counters?

I thought of this approach, but from code I see it resets the current m_supportedCounters counter list -- which will not help, as it clears the existing list ?

    if (always_check_supported_counters)
    {
        m_supportedCounters.clear();
    }

Removing the check will cause it check supported counter each time adding an object. I am afraid it will cause performance degradation. Could you please add one more attribute like dont_clear_support_counter and set it to true for macsec counter?

Added a new flag 'dont_clear_support_counter', do review
