* Publish new board file for upcoming release.
* Add RGB capabilites.

* Improve RGB LED Driver

Replaces the use of the `LED_BUILTIN` variable by creating a new variable called `RGB_BUILTIN`. On boards with both a regular LED and RGB LED, this change provides functionality to control either LED.

The `LED_BRIGHTNESS` variable is changed to `RGB_BRIGHTNESS`, which aligns more closely with the `RGB_BUILTIN` variable name.

`BOARD_HAS_NEOPIXEL` is no longer necessary; it is replaced by `RGB_BUILTIN`.

* Update BlinkRGB example

Update example code for changes with the RGB driver:
- Replace `LED_BUILTIN` and `BOARD_HAS_NEOPIXEL` with `RGB_BUILTIN`
- Replace `LED_BRIGHTNESS` with `RGB_BRIGHTNESS`

* Update board variants

Update board variants for changes with the RGB driver:
- Remove `BOARD_HAS_NEOPIXEL`
- Define `RGB_BUILTIN` pin
- Replace `LED_BRIGHTNESS` with `RGB_BRIGHTNESS` to align with `RGB_BUILTIN` name

- also update adafruit esp32s3 menu to match latest esp32s3dev one

Description of Change

This PR adds support for Espoir, a mikroBUS PoE+ devboard, by Connaxio inc. However, the ESP32-MINI-1 is a single core CPU, so Connaxio will provide the builds for its devboard until single core CPUs are officially supported. Adding these modifications to the official repository will limit discrepancies between Connaxio's fork and the main repo.

Tests scenarios

Tests include Ethernet, SPI, USB, I2C, UART (1-wire).

* Add new board XIAO_WIFI

Implemented a new method for allowing folks to preserve their TinyUF2 bootloader setup when flashing their boards via Arduino IDE, without being locked out of not using it if they want to use a different partition.

Adafruit had already added support for keeping (reflashing) the TinyUF2 bootloader when flashing via Arduino IDE (thanks @Ladyada ), but the issue with it is it doesn't allow users to not choose to use it. Even if they select a specific partition scheme from the partition drop down list, it ignores that selection and only does the TinyUF2 partitioning/bootloader thing.

We wanted to let users choose between keeping their TinyUF2 partitioning and bootloader, or choose another partition scheme and have the TinyUF2 support disabled and just operate like they would expect.

We've implemented this by adding the TinyUF2 support as a partition scheme option, and using these build options in platform.txt to choose to use teh UF2 path or use the standard path.

Add support for the Trueverit Universal IoT Driver MK III (https://www.trueverit.com/)

The board will be released on market using electronic distributors soon, as the other one board added via #5269

This new board (referred as MK III) has onboard Texas Instruments RTL8201 Eth PHY chip.

Fixed wrong SCK and MISO pins for TinyS2

* add AirM2M_CORE_ESP32C3 board
