runtime-rs: remove unnecessary Send/Sync trait implement

Send and Sync are automatically derived traits,
if a type is composed entirely of Send or Sync types, then it is Send or Sync.
Almost all primitives are Send and Sync,
so we don't need to implement them manually most of the time.

Fixes: #6307
