Marker traits for enabling Send and Sync requirements based on the
target family.
Normally we want to require real core::marker::Send and
core::marker::Sync for most of the types, however, the Web API bindings
can not support those, and in the Web setting, the spawning of async tasks
does not currently require those either.
So we turn off the core::marker::Send and core::marker::Sync
requirements for the Web targets using these Send and Sync traits.
