[BUG] Fan Control Server doesn't set PercentSetting when fan mode is set to "FanModeEnum::kOn"

[erwinpan1]

Reproduction steps

According to Fan Control Cluster's spec , PercentSetting and SpeedSetting should be set to High value when Fan Mode is set to On (or FanModeEnum::kOn).

4.4.6.1.3. On Value
If a client attempts to write a value of On, the attribute SHALL be set to High.

However, in current MatterFanControlClusterServerAttributeChangedCallback, only FanModeEnum::kOff and FanModeEnum::kAuto are handled.

Current codes:

void MatterFanControlClusterServerAttributeChangedCallback(const app::ConcreteAttributePath & attributePath)
{
    switch (attributePath.mAttributeId)
    {
    case FanMode::Id: {
        FanModeEnum mode;
        EmberAfStatus status = FanMode::Get(attributePath.mEndpointId, &mode);
        VerifyOrReturn(EMBER_ZCL_STATUS_SUCCESS == status);

        // Setting the FanMode value to Off SHALL set the values of PercentSetting, PercentCurrent,
        // SpeedSetting, SpeedCurrent attributes to 0 (zero).
        if (mode == FanModeEnum::kOff)
        {
...
        }

        // Setting the attribute value to Auto SHALL set the values of PercentSetting, SpeedSetting (if present)
        // to null.
        if (mode == FanModeEnum::kAuto)
        {
...
        }
        break;
    }
