SKR Mini E3 Creality Values for TMC

As a follow up to #15115, this PR adds default TMC RMS current values for the CR-10, CR-10S, CR-10 Mini and Ender-5 since stepper motors were easily identifiable online.

Note: Stock motors are rated from the manufacturer using peak values instead of RMS (See bigtreetech/BIGTREETECH-SKR-mini-E3#22 (comment) and this gist from @knoopx), which is why these values are less than the advertised ratings of 840mA for 34mm and 1000mA for 40mm steppers.
