Joe Tsai fd4c605bfb internal: simplify ExtensionInfo initialization ... This CL: * Make the meaning of impl/ExtensionInfo.goType consistent. Before, it was sometimes a T and other times a []T depending on the current state of initialization. Change it so that it is the constructor's responsibility to pass in a []T if it is repeated. * Make internal/filetype responsible for constructing a []T for repeated extension fields. * Makes filedesc/Extension.Cardinality one of the eagerly initialized pieces of information since it is useful to internal/filetype. * Unify ExtensionInfo.desc and ExtensionInfo.tdesc.ExtensionField, which held the same information. * Remove the internal implementation for impl.X.ExtensionDescFromType since we are dropping support for this from v1.
