Kconfig: Change default CANbus frequency to 1000000

Browse Source 
Change the default CANbus frequency from 500000 to 1000000.  A higher
frequency allows for greater data transfer rates, lower latency of
messages, and should overall be more robust.

## Changes
20230530: The default canbus frequency in "make menuconfig" is
now 1000000. If using canbus and using canbus with some other
frequency is required, then be sure to select "Enable extra low-level
configuration options" and specify the desired "CAN bus speed" in
"make menuconfig" when compiling and flashing the micro-controller.
20230525: `SHAPER_CALIBRATE` command immediately applies input shaper
parameters if `[input_shaper]` was enabled already.
