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.
