[issue24450] Add gi_yieldfrom calculated property to generator object

[Nick Coghlan]

Nick Coghlan added the comment:

Marking this as dependent on issue 24400, as that refactors the PEP 492 implementation to make coroutines their own type (albeit one that shares a memory layout and some attribute names with generators at the C layer).

I'd suggest cr_await as the calculated property for coroutines that corresponds to gi_yieldfrom for generators.
