Add internal EMAC support for ESP32-S31, including: - HAL/LL layer: emac_ll, emac_hal, emac_clk, emac_periph for S31 - SOC layer: register structs, soc_caps, peripherals linker script, interrupt definitions - MAC driver: clock source configuration via Kconfig, GPIO/DMA adaptations, PHY register defs for clause-45 MDIO - Ethernet examples updated for S31 (basic, build-test-rules, PTP readme) - Refactored existing ESP32/ESP32-P4 EMAC code for shared patterns (emac_clk extraction, struct alignment, periph descriptor cleanup)
