py/emitglue: Provide a truncated mp_raw_code_t for non-asm code.

Browse Source 
The `asm_n_pos_args` and `asm_type_sig` members of `mp_raw_code_t` are only
used for raw codes of type MP_CODE_NATIVE_ASM, which are rare, for example
in frozen code.  So using a truncated `mp_raw_code_t` in these cases helps
to reduce frozen code size on targets that have MICROPY_EMIT_INLINE_ASM
enabled.

With this, change in firmware size of RPI_PICO builds is -648.
