boards: add Realtek RTL8721Dx and RTL8720F board configurations

Browse source 
Add board-level support for two Realtek Ameba WHC evaluation boards:

  - pke8721daf (RTL8721Dx)
  - rtl8720f_evb (RTL8720F)

Each board provides:
  - defconfig for NSH with WiFi networking support
  - CMakeLists.txt (make-only build helper that fails fast on cmake)
  - Board-specific bring-up and initialization (leds, SDIO, flash)
  - Scripts/Make.defs including the IC-level build fragment and the
    make flash target (tools/ameba/Config.mk)
