What's new in ANNIVERSARY 2023 (20231202) AML2.0 Edition

* Arbitrary rectangular NxM mesh leveling density (AML2.0)
* Mesh size and mesh density are also saved in UBL slots (AML2.0)
* Adds Custom g-code C29 M for maximize and C29 C for center mesh area (AML2.0)
* Larger font for numeric values in bed tramming wizard
* Run-out icon blink is disabled if run-out sensor is disabled
* Mesh viewer is now able to show a mesh with NAN points
* Disables UBL_SAVE_ACTIVE_ON_M500 and ZOFFSET_SAVE_SETTINGS for AML2.0 compatibility
* Define PREHEAT_TIME_HOTEND_MS 7500 for compatibility with high temperature thermistors

**New in source code:**
* ProUI extension support for Monochrome LCD displays (CR10 Type, TFT MarlinUI, etc)
* ProUI extension support for MarlinUI touch screens
* C104 support can be removed for better special temperature sensor compatibility
* Allows to use bed tramming wizard without a leveling system
* Bed tramming wizard can be disabled for reduce program memory size
* Allows compile without a bed probe or leveling system
* Fix sound on encoder tick when SPEAKER is enabled
* Fix sound alarm on thermal runaway when SPEAKER is enabled
* Increased board support (Octopus Pro)
* Moved some text strings to language files for better translation
* New menu system with better memory allocation
* Code optimization to reduce program memory size

**From Marlin Bugfix**
* Automatic minimum planner junction speed (#26198)
* Nonlinear Extrusion Control (M592) (#26127)
* More precision in G30 output (#26255)
* Allow arbitrary BLOCK_BUFFER_SIZE
* Fixes for G2/G3 arcs (#26170)
