[WIP] Add support for Sovol SV06 Plus Touchscreen

[saddfox]

Description

This PR adds support for the Sovol SV06 Plus screen with stock firmware. Based on Sovol's source code targeting Marlin 2.0.9.2. Both Marlin and LCD sources are available here.
The LCD code is mostly untouched from source, I have done some basic work cleaning up the integration. It builds and runs on SV06P and should not affect other machines.
The integration is currently using lots of #if preprocessor directives and not being pretty. At the very least some code should be moved from core to lcd functions. There is some overlap in functionality with ia_creality extui module so maybe we can lean into that instead.

The screen used is marked as CXSW043_004, not sure if it's a genuine DWIN product or a compatible clone. The same screen seems to be used by Ender 7 and Sermoon D1.

Requirements

Requires a stock SV06 Plus with Sovol v1.3.1 MB and stock touchscreen.

Benefits

Allows using the stock screen with Marlin.

updated config in first post.

Is there any work that needs to be done with this for approval? I have been testing it with success so far, I was going to start looking at how to integrate host actions and progress on the screen based on this PR.

As far as I am concerned it's mostly finished, maybe some slight cleanups here and there. I have been using it without issue for some time now.
The problem I think mostly comes down to whether it even makes sense to include this upstream. While the integration has been cleaned up significantly, it's still adding some extra code to core Marlin and I am not sure doing that for a single printer is reasonable.

For host actions and print progress you may get some ideas from this repo https://github.com/smkent/sovol-sv06-plus-firmware

Thanks, I might pull that work into yours for now. I have been running yours with a couple of small changes without issue.

Wherever possible we want to convert custom LCD hooks into ExtUI callbacks, and generally moving all displays that want to receive common event updates over to the ExtUI API. Any new displays added to Marlin that can't do MarlinUI should use an ExtUI layer, and should feel free to add onto it as they require. We'll apply such conversions as time allows.

Has anyone got Sovol SV06 Plus configurations to go with this? If so, we should get a PR set up over at the Configurations repo. Anyway, I'll merge this as-is and we can continue to refine as needed. Add it to the list for testers of 2.1.3-beta.

@thinkyhead there is a config in the first post

I can test if it still runs fine and open a PR with config sometime next week.
