Improve error handling in validation so distinct error types are returned for verification #598

Bug Summary
Describe the bug:
Project validation is the only component that does not have it's own error type in errors.go. The error messages are currently constructed as strings which makes it difficult to verify error types when testing the negative path.
Also, the ValidateDevfileData function returns a concatenation of error strings. We should switch to returning a multierror which was recently introduced in #577
