Evaluates fa on the supplied execution context and shifts evaluation
back to the default execution environment of F at the completion of fa,
regardless of success or failure.
The primary use case for this method is executing blocking code on a dedicated execution context.
Execution context where the evaluation has to be scheduled
Computation to evaluate using ec
Asynchronous boundary described as an effectful F[_] that
can be used in flatMap chains to "shift" the continuation
of the run-loop to another thread or call stack.

This is the Async.shift operation, without the need for an
ExecutionContext taken as a parameter.
ContextShift provides support for shifting execution.
The
shiftmethod inserts an asynchronous boundary, which moves execution from the calling thread to the default execution environment ofF.The
evalOnmethod provides a way to evaluate a task on a specific execution context, shifting back to the default execution context after the task completes.This is NOT a type class, as it does not have the coherence requirement.
