More incorrect attribute defaults (CON-1137)

Temperature Measurement: https://github.com/espressif/esp-matter/blob/main/components/esp_matter/esp_matter_cluster.h#L630

    config() : cluster_revision(4), measured_value(), min_measured_value(27315), max_measured_value(32767) {}

Last two should be NULL.

2.3.4.2. MinMeasuredValue Attribute
This attribute SHALL indicate the minimum value of MeasuredValue that is capable of being mea­
sured. See Measured Value for more details.
The null value indicates that the value is not available.
2.3.4.3. MaxMeasuredValue Attribute
This attribute indicates the maximum value of MeasuredValue that is capable of being measured.
See Measured Value for more details.
The null value indicates that the value is not available.

Relative Humidity https://github.com/espressif/esp-matter/blob/main/components/esp_matter/esp_matter_cluster.h#L642

    config() : cluster_revision(3), measured_value(), min_measured_value(0), max_measured_value(10000) {}

Last two should be NULL

2.6.4.2. MinMeasuredValue Attribute
The MinMeasuredValue attribute indicates the minimum value of MeasuredValue that can be mea­sured. 
The null value means this attribute is not defined. See Measured Value for more details.
2.6.4.3. MaxMeasuredValue Attribute
The MaxMeasuredValue attribute indicates the maximum value of MeasuredValue that can be mea­sured. 
The null value means this attribute is not defined. See Measured Value for more details.

More auditing of these default values is needed, I keep finding problems.
