Add RTL8201-based wESP32 rev7 Ethernet option

[snoack]

Add a separate Ethernet board type for wESP32 rev7 and later boards, which use the RTL8201 PHY instead of the LAN8720 used by earlier revisions.

Summary by CodeRabbit

• New Features
  • Added support for WESP32 Rev 7 with RTL8201 Ethernet PHY
  • Updated Ethernet Type selection dropdown to distinguish between WESP32 Rev 6 and earlier versus Rev 7 and later variants

Walkthrough

This PR adds support for WESP32 Rev 7 with RTL8201 Ethernet PHY. It introduces a new Ethernet type constant, defines its board-level pin and PHY configuration, updates existing WESP32 entries to clarify Rev 6 compatibility, and splits the Ethernet Type dropdown to allow users to select the appropriate hardware variant.

Changes

WESP32 Rev 7 (RTL8201) Ethernet Board Support

Layer / File(s)	Summary
Ethernet type definition wled00/const.h	WLED_NUM_ETH_TYPES incremented from 16 to 17; new macro WLED_ETH_WESP32_RTL8201 added with ID value 16.
Board configuration and PHY mapping wled00/network.cpp	Existing WESP32 entry comment updated to specify "rev 6 and earlier"; new ethernetBoards[] entry for WLED_ETH_WESP32_RTL8201 defines RTL8201 PHY with MDC/MDIO on GPIO16/GPIO17 and ETH_CLOCK_GPIO0_IN clock mode.
Ethernet Type UI dropdown wled00/data/settings_wifi.htm	Single WESP32 option replaced with two revision-specific options: "WESP32 (Rev 6 and earlier)" and "WESP32 (Rev 7 and later)" with distinct values.

• wled/WLED#4602: Directly addresses the request for explicit WESP32 Rev 7 (RTL8201) support with the new constant, board configuration, and UI dropdown option.

Possibly related PRs

• wled/WLED#5608: Adds compile-time validation to ensure ethernetBoards[] stays synchronized with WLED_NUM_ETH_TYPES—directly relevant to the type count and array entry changes in this PR.
• wled/WLED#5156: Extends the Ethernet type system with new constants in const.h, entries in network.cpp's ethernetBoards[], and UI dropdown updates—using the same pattern as this PR.
