meson: Update targets in cross-files for bigger platforms

* WinChipHead CH579, Puya PY32F0, Arterytek AT32F43x target drivers
  were the most recently added, and they are self-contained
* GD32/STM32F103CB-based adapters cannot fit all of the drivers,
  so some are disabled by default, requiring makeflags or meson flags to opt-in.
* Enable such drivers by default in meson builds for adapters with 256 KiB
  of internal flash or more, to provide users a full feature set of target drivers
  and to leverage CI compile-checking code at least on those adapters.
