PlatformIO support for new Raspberry Pi RP2350 microcontroller boards

[znmeb]

I have a few boards with the new RP2350 microcontroller and want to get CForth running on them. The PlatformIO support for these boards is in a pre-release state, but I have a few of the boards and managed to get CForth to build and upload to a SparkFun Pro Micro RP2350 today. My test code is here:.

I'm testing in containers on Fedora Silverblue at the moment so I have to do some finagling to get the uploads to work, but once all the upstream releases and Linux udev rules are sorted out, it should be possible to run this in Visual Studio Code with the PlatformIO extension on any supported platform.
