boards: shields: add g1120b0mipi watch display

Add g1120b0mipi watch display to shields. This shield is currently
supported with the RT595 and RT1170 EVK. The shield contains a 400x392
circular OLED watch display, with an integrated RM67162 display controller

Note that the touchscreen IC can be driven by the FT5336 driver, with the
following changes:

- the FT3267 reports touch data as inverted from the FT5336, so
  LVGL must be made aware of this via CONFIG_LV_Z_POINTER_KSCAN_INVERT_Y
- the FT3267 reports the X and Y coordinates as swapped from the FT5336.
  To resolve this, the RM67162 driver reports the display as rotated by
  90 degrees.
