FabGL (+lvgl ?) display support

**Describe the problem you have/What new integration you would like**

Actually we don't have analog display options available in ESPHome.
Now there is a lvgl component. FabGL library support (which have lvgl support) would be great.

There is also another libraries doing composite or vga video but FabGL have supported esp boards.

**Please describe your use case for this integration and alternatives you've tried:**

Retrofitting existing monitors, TVs, terminals, etc.
Thinking about RVs, arcade cabinets. hotels rooms, CCTV and more. mainly retrofitting purposes.

**Additional context**

FabGL's documentation:

http://www.fabglib.org/

Start with FabGL's documentation and the existing ESPHome LVGL component mentioned in the request. Determine the supported ESP boards, display use cases, and integration boundaries before defining what implementation files, tests, and acceptance criteria would be needed; no repository files or tests are named here.
