Add help text to the esp32h2/esp32h21/esp32h4 Kconfig.mac explaining
that these chips only consume one universally administered MAC address:
the IEEE 802.154 EUI-64 is derived from the base MAC and MAC_EXT, and
Bluetooth reuses the base MAC as-is (no BT offset, since there is no
Wi-Fi).
Add a matching 1-MAC derivation table and note to misc_system_api.rst
(EN and zh_CN) under a new `.. only:: esp32h2 or esp32h21 or esp32h4`
block, and exclude these targets from the generic 4/2 table.
Add an esp32s31-only note stating that the "Four" option may only be
used with a customer-provided custom base MAC range, since ESP32-S31
only provides two universally administered MAC addresses in eFuse.
