raul_chen cce73da215 Documentation: rework Realtek RTL8721Dx and RTL8720F chip/board pages
Rewrite the RTL8721Dx / PKE8721DAF and RTL8720F / RTL8720F-EVB pages against
the official Realtek product specifications, from an application-developer
point of view:

- Describe the application core NuttX runs on -- an Arm Cortex-M55-compatible
  core, up to 345 MHz on RTL8721Dx (KM4) and up to 320 MHz on RTL8720F (KM4TZ)
  -- and the on-chip memory, instead of the internal multi-core / IPC
  arrangement that is not relevant to application developers.
- Fix the RTL8721Dx SRAM size: 512 KB (was incorrectly documented as 288 KB).
- Add per-part memory (RTL8721DAF and RTL8720FBF: 4 MB NOR flash, 512 KB
  SRAM), wireless (RTL8721Dx: Wi-Fi 4 dual-band + BLE; RTL8720F: Wi-Fi 6
  2.4 GHz + BLE + Thread), peripheral and security highlights.
