* Add GFX overlay to UBL mesh edit

Fixed misplaced HAS_TEMP_BED in dogm_bitmaps.h

rename _lcd_babystep_zoffset_overlay to _lcd_zoffset_overlay_gfx and move it out of BABYSTEP_ZPROBE_OFFSET to we can use it for over things. Add this function into UBL mesh edit screen.

update all Configuration.h to add ENABLE_MESH_EDIT_GFX_OVERLAY

* Add Sanity to UBL  insanity

Need to check for DOGLCD  otherwise error out.

* Get UBL Mesh Generation, Mesh Save & Mesh Load working with 32-Bit platforms

* clean up read_data() and write_data() for non-LPC1768 HAL's

* Get read_data() and write_data() return codes consistent

All HAL's read_data() and write_data() return false if they succeed.

* Get read_data() and write_data() return codes to be consistent

Make read_data() and write_data() return true if an error happens.

* Say UBL is now checked out on machine types in default Configuration.h file.

Based on #7883 by @studiodyne

get rid of twi.h

move to board files

Same as #7728 but for 2.0.x,
Lot of cleanup and remove references in whole code to other "LED files" than leds.h. Now will be much easier to add next drivers/libraries. e.g. FastLED. But bad news, currently FastLED is suporting only RGB devices (no RGBW)
