Update helpers and drivers to handle LVGLv7 and v8 versions (#161)
* [lvgl_helpers] Cleanup and misc code cleanup

Checks for SPI_HOST_MAX symbol before using it.

Rename lvgl_driver_init to lvgl_interface_init because it now only initialize
the interface bus for display drivers, we still need to remove the indev
drivers from here.

Use types defined in spi_types.h for spi host (spi_host_device_t) and
spi dma channels (spi_dma_chan_t).

Also add a couple of symbols to avoid using magic numbers

* [lvgl_helpers] Reduce usage of if defined in lvgl_interface_init

* [lvgl_helpers] Fix spi dma channel for ESP-IDF versions <= 4.2

* [examples] Update hello_world to call lvgl_interface_init

* Add lvgl_get_display_buffer_size helper

This helper will allow us to get the calculated display buffer size instead of using a global symbol.

* Implement lvgl_get_display_buffer_size

This API will be used to get the calculation of display buffer size.

* Delete DISP_BUF_SIZE symbols

The same functionality is handled by lvgl_get_display_buffer_size

* Move SPI max transfer size calculation to helper

Use calculate_spi_max_transfer_size to calculate the SPI max transfer size for the SPI master configuration

* Remove SPI_BUS_MAX_TRANSFER_SZ definition

Same functionality is now handled in calculate_spi_max_transfer_size

* Update display buffer size calculation

Use lvgl_get_display_buffer_size helper instead of DISP_BUF_SIZE symbol

* Update example to LVGL v8

Add comments about changes from:
- LVGL v7 to LVGL v8
- Configuration helpers and display drivers

* Update lvgl_helpers.c

* Update sh1107 driver

* Update EVE driver

Check for symbols used in previous implementations before trying to use them
and add a fallback temporary implementation when not found.

The falback implementation isn't tested with hardware.

Symbols:
- DISP_BUF_SIZE
- SPI_TRANSFER_SIZE

* Update uc8151d driver

* Update jd79653a driver

* Update ra8875 driver

* Update il3820.h

Check for LV_HOR_RES_MAX and LV_VER_RES_MAX before trying to use them

* Update lvgl_helpers.c

Check for ESP-IDF version before trying to use spi_dma_chan_t type
