Marlin is an optimized firmware for RepRap 3D printers based on the Arduino platform. Many commercial 3D printers come with Marlin installed. Check with your vendor if you need source code for your specific machine.
Suppressible LCD contrast warning: Users don't need to know or care about something their LCD doesn't support, so let's make it easier to silence the warning. In fact, this entire warning could be removed, but I left it here anyway.
Suppressible Z_SAFE_HOMING warning: Homing with a probe to the right of a hotend usually doesn't require homing to the center of the bed if homing to X min (i.e.: Prusa MK2/3, Ender-3, etc.), so let's make it easier to silence the warning.
Suppressible user feedback warning: External G-code senders that communicate via serial can handle / remap G-codes as they are processed (like with BTT's TFT firmware), so it'd be nice to have the option to silence this warning on Marlin's side.
Benefits
Users won't have to venture into Warnings.cpp to override frequently encountered warnings and this is more in line with how we allow other warnings to be disabled without diving into core Marlin files.
