feat: tagged_return attribute (#11530) 
This PR introduces the new `tagged_return` attribute. It allows users to
mark `extern` declarations to be guaranteed to always return `tagged`
return values. Unlike with `object` or `tobject` the compiler does not
emit reference counting operations for them. In the future information
from this attribute will be used for a more powerful analysis to remove
reference counts when possible.
