stmhal: Reduce size of ESPRUINO_PICO build so it fits in flash.
The default frozen modules are no longer included (but users can still specify their own via FROZEN_MPY_DIR), complex numbers are disabled and so are the native, viper and asm_thumb emitters. Users needing these features can tune the build to disable other things.
