Summary

Fixes #3288 by making error messages more specific to how the user tried to initialize the model. We have messages now for full init, partial init, init with zero, and init with a range.

Intended Effect

Make the error messages a user sees slightly nicer

How to Verify

The following stan model with fully specified values will print out

Rejecting initial value:
  Error evaluating the log probability at the initial value.
Exception:  (in 'src/test/test-models/good/services/test_fail.stan', line 5, column 2 to column 13)
User-specified initialization failed.
 Try specifying new initial values, using partially specialized initialization, reducing the range of constrained values, or reparameterizing the model.

parameters {
  real a;
}
model {
  reject();
}
