[TEP-0089] Enable SPIRE for signing taskrun results in alpha.

Breaking down PR tektoncd#4759 originally proposed by @pxp928 to address TEP-0089 according @lumjjb suggestions. Plan for breaking down PR is PR 1.1: api PR 1.2: entrypointer (+cmd line + test/entrypointer) Entrypoint takes results and signs the results (termination message). PR 1.3: reconciler + pod + cmd/controller + integration tests Controller will verify the signed result. This commit corresponds to 1.3 above.
