Add conversion for v1 Pipeline

[JeromeJu]

Changes

This commit adds conversion functions between v1beta1 and v1 Pipeline. It does not handle fields deprecated in v1beta1 that will not be present in v1. It implements ConvertTo and ConvertFrom for v1beta1 Pipeline, and leaves these functions unimplemented for v1 Pipeline, since it is the highest known version.

Conversions for all types are basically deep copies, rather than using the same struct definition for both API versions. This will allow us to iterate on v1 without making additional changes to v1beta1, after v1 is the stored version.

Handle resources regarding #5253

Part of #4986 /kind misc
