Add BGA/CSP footprints for new ST STM32 microcontrollers

This MR adds a few CSPs and BGAs for new additions in ST's STM32 microcontroller series.

The footprints are generated from definitions added in footprint generator MR kicad-footprint-generator!1089 (merged)

These footprints are needed for new symbols from symbol generator MR kicad-library-utils!532
