Supporting "natmod" with minimal other code

[jepler]

Right now, the mp_fun_table in nativeglue.c is gated by MICROPY_EMIT_NATIVE. However, it appears other things are also gated on this, like NEED_METHOD_TABLE in compile.c, as well as e.g., py/emit*.c.

Is it possible to reduce the flash overhead of only enabling loading natmods from mpy files, without other things like the @micropython.native decorator? If there's not an existing configuration option for this, any guidance on which parts of EMIT_NATIVE are actually needed for this, so I can hack on it?

You mean something like #18596?

Ooh that's pretty much the pony I wanted. I was looking at circuitpython which is not too up to date. Thanks, something to look forward to when another merge from microPython is done someday.
