CESQL: clarify behaviours of errors in OR expressions

[Cali0707]

Currently, in the Go SDK V2, (type = 'dev.knative.example') OR (missingattribute = 'test') results in an error, even if type = 'dev.knative.example', so long as missingattribute is not set on the event. However, if this implementation were changed to eagerly return on a true value (which an optimized implementation should do), then the return value would be true.

We should

1. Clarify whether the evaluation should be eager or not
2. Open issues to any SDKs with an implementation that does not match the new, clarified spec
