ci: update toolchain for Espressif

[fdcavalcanti]

Summary

• documentation: update Xtensa ESP32|S2|S3 toolchain version

Updates the instructions to install the ESP toolchain 14.2.0.

• ci: update ESP32 Xtensa compiler version

Updates ESP32, ESP32S2 and ESP32S3 compiler version to 14.2.0 of 20241119.

Hi all,

This PR updates the ESP32, ESP32S2 and ESP32S3 compiler version from version 12.2.0 to 14.2.0.

A difference that might be observed from the previous version is that instead of downloading and extracting one toolchain file for each SoC, we just download one file that contains all toolchains required. That simplifies the CI Dockerfile a little bit but has all xtensa-esp32, xtensa-esp32s2 and xtensa-esp32s3 under one directory.

Impact

• Impact on user: No.
• Impact on build: Yes, changes the CI build system by updating toolchain version.
• Impact on hardware: No.
• Impact on documentation: Yes, updates documentation for ESP32, ESP32S2 and ESP32S3.
• Impact on security: No.
• Impact on compatibility: No.

Testing

Built the Dockerfile locally and verified all gcc and g++ are available.

Building

• cd tools/ci/docker/linux
