🚸 Add Input Shaping with I2S_STEPPER_STREAM warning

[thisiskeithb]

Description

As the title states, add an Input Shaping with I2S_STEPPER_STREAM warning for ESP32-based motherboards like the MKS TinyBee.

The warning is a bit inaccurate since it's a known issue that these are incompatible (and it just came up again on Discord), but I wanted to match the existing FT_MOTION + I2S_STEPPER_STREAM warning:

Marlin/Marlin/src/inc/Warnings.cpp

Lines 854 to 859 in eb781af

	/**
	* Fixed-Time Motion
	*/
	#if ALL(FT_MOTION, I2S_STEPPER_STREAM)
	#warning "FT_MOTION has not been tested with I2S_STEPPER_STREAM."
	#endif

I originally tried to sanity check this in #25632, but the PR got hijacked and turned into something else, so it was closed.

Requirements

Any ESP32 motherboard like the MKS TinyBee with I2S_STEPPER_STREAM and HAS_ZV_SHAPING (INPUT_SHAPING_X / INPUT_SHAPING_Y)

Benefits

Warn users that these settings may be incompatible (but we know they're not).

Configurations

Any ESP32 motherboard like the MKS TinyBee with I2S_STEPPER_STREAM and HAS_ZV_SHAPING (INPUT_SHAPING_X / INPUT_SHAPING_Y)
