Google APIs 45b363d3ab Refactor the CEL protos to reflect their use as cross-language
data representations used within various open source libraries.

There is no CEL Google API per se, and as such any reference to
one has been removed from the proto libraries including the GAPIC
client code generation.

There is a gRPC service defined among the protos which is used for
driving conformance testing in a cross-language compatible manner.
