Description

the stream scheduler works by adapting senders to the stream domain so that their operation states are in managed memory, and so that completion is executed on the device.

there are two types of senders: those that can be introspected and those that can't. if a sender can be introspected, it makes available its tag type. for instance, the sender just() has a tag type of just_t. if a sender cannot be introspected, it does not make a tag type available.

the stream sender adaptor is currently assuming that all senders are introspect-able. this is a mistake. this pr changes the stream sender adaptor to work with senders that cannot be introspected.

note: the test for this fix is currently on an if(false) branch because it uses starts_on, and starts_on is currently broken for the stream scheduler. a future pr will fix starts_on and enable this test.
