Mount Performance

Fixed a bug where RA would jump a little at the beginning of a GoTo operation.
Re-enabled support for different microstepping settings for slewing and tracking.
Allowed microstep settings to be defined in the local config.
Separated guide stepper from DEC stepper so that guiding doesn't change DEC coordinates.
Fixed a bug where tracking speed was not calculated correctly, nor adjusted on the fly when RA Steps/deg were changed.
Made DEC driver be in Guide microstepping mode unless slewing.

Steppers/Drivers

Removed connection test check and made it standard.
Switched motors to normal mode (better perf), but allowed silent mode through XX_UART_STEALTH_MODE defines.
Fixes RMS current setting for TMC2209 UART to be more accurate and consistent
Disables i_scale_analog (aka "USE_VREF") by default so that results are more consistent between users. rms_current will no longer depend on Vref, unless specifically configured by the user.
Changes UART baud rate to 19200 rather than the default of 115200 - the Rx channel was too unreliable and repeatedly had CRC errors at the higher baud rate.
Adds a test method for visual confirmation of Tx-only UART connectivity. At boot (before tracking starts), each axis will rotate slightly in each direction driven purely by UART commands. If the user sees the movement, they know UART Tx is functioning.
