Fix MKS LVGL includes

[thisiskeithb]

Requirements

MKS Robin Nano with "dumb" TFT35: env:mks_robin_nano35 and TFT_LITTLE_VGL_UI.

Description

This PR corrects some include path errors in MKS' LVGL UI. Compiling still results in a bunch of errors, but at least the includes have been fixed:

Here's a ready-to-build branch for a Tevo Nereus with LVGL enabled to view/test said errors.

Benefits

This will start to get the ball rolling on successfully compiling for MKS' new LVGL UI on a Robin Nano + TFT35.

This board/LCD combo is used in the Tevo Nereus, which we have a config for, but to get it into Marlin originally, we had to use FSMC_GRAPHICAL_TFT and TOUCH_BUTTONS (and users lost the original "MKS UI" that TFT_LITTLE_VGL_UI now replaces).

Would it make sense to create a copy of the config and call it "Tevo Nereus LVGL" so users have a choice? It'd allow us to easily add it to the CI tests at least.

I basically have the "Tevo Nereus LVGL" config ready to go as mentioned in the above post, but I had to disable a bunch of features like ADVANCED_PAUSE_FEATURE/etc. since it wouldn't pass sanity checks. I haven't looked into if sanity checks needed to be updated or if they are in fact, no longer compatible when LVGL is enabled.
