feat(esptool): Upgrade to esptool v5

[lucasssvaz]

This pull request includes updates to the ESP32 platform files, focusing on upgrading the esptool_py tool version, improving argument consistency, and enhancing functionality for binary merging and flashing. The changes ensure compatibility with the latest tool version and refine command-line arguments for clarity and correctness.

Version Upgrade and Compatibility Updates:

• Updated esptool_py version from 4.9.dev3 to 5.0.dev1 in package/package_esp32_index.template.json, including URLs, checksums, and file sizes for various system architectures.

Command Argument Improvements:

• Fixed inconsistencies in argument names by replacing underscores (_) with hyphens (-) for options like --flash_mode, --flash_freq, and --flash_size in platform.txt.

Binary Merging Enhancements:

• Improved the binary merge command by replacing merge_bin with merge-bin and introducing the --pad-to-size argument for better handling of flash size padding in platform.txt.

Please explain the arguments a bit. It is not clear what each one is. Is base_folder the output? Where does json_path come from?

[lucasssvaz]

@me-no-dev I've reworked the script to be way more flexible and useful. PTAL if there is anything missing.
