Hello, Could you please add KINGMODEL support to the AM32 targets? Thank you very much.

This PR is ready for review. Thanks.

@hokbin can you give us some details about this esc? Is this sold commerically? We are hesitant about adding targets for esc's that we do not know anything about.

@AlkaMotors Thanks for the caution — that’s reasonable. We don’t have full documentation/commercial details on this ESC either, and we don’t want to imply it’s a “supported/officially validated” target.
The reason we’d like to add it is narrower: a small number of users already have this hardware, and without a target they can’t update firmware / apply fixes through the normal toolchain. So this is more about user convenience for existing owners than promoting the ESC.

The firmware name is "KINGMODEL_F421" and the Ali listing contains a dire warning: "This AM32 ESC cannot be flashed with other firmware. Flashing incompatible firmware will cause the ESC to be bricked."

I'm not sure that claim is true, but I also don't know how to restore the original firmware if it is.
