STM data generator for probe-rs

This tool uses stm32-data-generated and some custom code to generate presumably complete device lists and correct memory maps for probe-rs.

To use the tool, update commit hashes in d.ps1, then run ./d.ps1 download-all and ./d.ps1 gen.

Then, use the contents of the output folder to update probe-rs.

Please review changes carefully. Any change in the memory map needs to be double-checked.
