Fix #8540

MK2_MULTIPLEXER does not require E2/E3 stepper pins

Does it?

[1.1.x] Adapt MESH_EDIT_GFX_OVERLAY

[1.1.x] Added optional NanoDLP Z movement synchronization

Addressing #8544

Implemented synchronization message output for NanoDLP printers (nanodlp.com).
If optional feature is enabled in `Configuration_adv.h`, Marlin will ouput "Z_move_comp" string to serial after completing any G0/G1 Z-axis movements. This feature patched on previous versions(1.0) is used by NanoDLP to synchronize Z-axis movement with projector exposure in DLP stereolithography printers.

[1.1.x] Make G26 work with other meshes too

Example Configuration.h files are not updated yet.   You need to cross
your settings over to the default Configuration.h file in the \Marlin
directory.   (UBL_G26_MESH_VALIDATION enablement has moved to a new
location in the file.)
