[FEATURE REQUEST]🦄Change ESP_DIRECT_SD to ESP_ONLY_SD for consistency

[luc-github]

in configuration.h

/* SD card connection
* ESP_NO_SD //(default)
* ESP_DIRECT_SD //Only your ESP board is connected to SDCard
* ESP_SHARED_SD //Printer SD Card is also connected to ESP3D
* Does your system has SD card and how it is connected to your ESP3D
*/

ESP_DIRECT_SD seems confusing for users and is often used when ESP_SHARED_SD should be used, the configurator must be updated also

Agreed, im trying to figure out what it means.

currently it says Your system has SD card and your ESP is connected to it using shared solution

What exactly is a shared solution? Does it simply mean the printer has a sd card? and we do not have to connect anything to the esp?
