Alessandro Gatti 42ea7bc32a py/mpstate: Make it possible for mpy-cross to set emitter options. ...

This commit introduces a way for mpy-cross to pass a set of options to
the chosen emitter.

This is achieved by adding an opaque pointer to the dynamic compiler
state structure that is only accessed by emitters that have a need to
receive options from mpy-cross when generating code.  That's a way to
make this feature possible without breaking any existing code or
emitter, and without re-engineering the compiler entry point function
(together with passing the options struct downstream until it's time to
emit code).

The main use case for this is letting the RV32 emitter know which
optional extensions it can generate code with, to be able to emit better
suited code for the platform in use.
