Escape double quotes and backslashes everywhere in the JSON output of get_board_details.sh to ensure that the output is a valid JSON.
Rewrite get_core_version.sh to properly separate each version component during processing. Export a Zephyr-compatible VERSION file if a filename is provided as the first argument.
Add the possibility of writing to platform.local.txt instead of boards.local.txt when the board variable is not set. This allows for global configuration settings that are not specific to any particular board to be saved.

The build.sh script now saves the build version to loader/VERSION (so it is picked up by the Zephyr build system) and updates the version field in both platform.local.txt and boards.local.txt. To ensure multiple boards share the same version, the build_all.sh script exports a global PINNED_CORE_VERSION environment variable so that get_core_version.sh can use it instead of generating a new version for each run.

This is step 1. for automatic flash of the loader if the onboard version is different from the one shipped with the core: passing the current build version in the USB descriptor as iConfig, so that it is available on the host side to check if the loader needs to be reflashed. For the legacy USB stack, the version is passed to USB drivers directly via the Kconfig option CONFIG_USB_CONFIGURATION_STRING_DESC. Boards using the new USB stack, like the Portenta C33, set this value via the USBD_DESC_CONFIG_DEFINE macro instead.
Add generic 'upload.artifacts.loader' and 'upload.artifacts.sketch' variables to platform.txt to allow for cleaner upload patterns and explicit file dependencies. Remove 'stm32flash' and 'adb' upload patterns, as they are not used by any of the supported boards. Also remove any '.erase' patterns, as all of them were empty anyway.

tracks https://github.com/arduino/arduino-renesas-bootloader/tree/zephyr_alt , allows consecutive uploads (loader+sketch)
For boards that have soft USB, use the new 'scripting-tools' tool to
check the USB configuration string reported by the board. If it does not
match the expected version, reflash the bootloader before uploading the
sketch.
Refactor loader and sketch commands so they can be reused in both the
bootloader and upload patterns. Note that {loader.cmd} should leave the
target waiting for the sketch upload, so {bootloader.pattern} has some
extra flags to make it exit after flashing the bootloader.
Supported tools:
- bossac
- dfu-util
- picotool

Switching to this core requires an updated bootloader. Since it will be flashed only if needed, the procedure is now: * Double click reset to enter bootloader mode * Burn bootloader * Wait until the blue led starts flashing * Double click reset to enter bootloader mode again * Upload sketch
