Ranges not being generated by zap

[chrisbeach59]

Problem
Thermostat.xml file contains the min and max values for
Temperature setpoints and limits but they do not appear in the generated .zap file
These were identified in #8878

Also the zap tool displays warnings about signed ints but does generate the correct code.

Matter spec seems to have removed the ranges

Proposed Solution
Follow up on these

I think this is almost everywhere the same issue

@chrisbeach59 I believe #330 fixed this.

Er, didn't mean to close. @chrisbeach59 please close if this now works as you expect?

@bzbarsky-apple OK To Close. I don't have rights to do so.
Thanks
