feat(lvgl_port): Initial support for ppa rendering in lvgl

      Mainly supports the following features:
       - color blend (simple fill)
       - color blend with opa
       - blend normal (blend with argb8888)
       - blend normal to color (color convert / memcpy)

+# MIPI DSI LCD Panel Example
+
+[esp_lcd](https://docs.espressif.com/projects/esp-idf/en/latest/esp32p4/api-reference/peripherals/lcd/dsi_lcd.html) supports MIPI DSI interfaced LCD panel, with frame buffer(s) managed by the driver itself.
+
+This example shows the general process of installing a MIPI DSI LCD driver, and displays a LVGL widget on the screen.
+
+## How to use the example
+
+### Hardware Required
+
+* An ESP development board, which with MIPI DSI peripheral supported
+* A general MIPI DSI LCD panel, with 2 data lanes and 1 clock lane, this example support [ILI9881C](https://components.espressif.com/components/espressif/esp_lcd_ili9881c) and [EK79007](https://components.espressif.com/components/espressif/esp_lcd_ek79007)
+* An USB cable for power supply and programming
+
+### Hardware Connection
+
+The connection between ESP Board and the LCD is as follows:

+
+Before testing your LCD, you also need to read your LCD spec carefully, and then adjust the values like "resolution" and "blank time" in the [main](./main/mipi_dsi_lcd_example_main.c) file.
+
+### Configure
+
+Run `idf.py menuconfig` and go to `Example Configuration`:
+
+* Choose the LCD model in `Select MIPI LCD model` according to your board.
+* Choose whether to `Use DMA2D to copy draw buffer to frame buffer` asynchronously. If you choose `No`, the draw buffer will be copied to the frame buffer synchronously by CPU.
+* Choose if you want to `Monitor Refresh Rate by GPIO`. If you choose `Yes`, then you can attach an oscilloscope or logic analyzer to the GPIO pin to monitor the Refresh Rate of the display.
+  Please note, the actual Refresh Rate should be **double** the square wave frequency.
+
+### Build and Flash
+
+Run `idf.py -p PORT build flash monitor` to build, flash and monitor the project. A LVGL widget should show up on the LCD as expected.
+
+The first time you run `idf.py` for the example will cost extra time as the build system needs to address the component dependencies and downloads the missing components from the ESP Component Registry into `managed_components` folder.
+
+(To exit the serial monitor, type ``Ctrl-]``.)
+
+See the [Getting Started Guide](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/index.html) for full steps to configure and use ESP-IDF to build projects.
+
