How or where can I find the details of the function "signal.internal.getToneFromPSD" that was called in "snr.m" of the signal processing toolbox?

It is in the internal package, as indicated by the name signal.internal.*. This means that the function is only intended for internal usage. Therefore this function is not documented and can be changed in the future. As to the details, it's a MATLAB file so you can look at it in the editor.
