Remove infra specific pipelines and enable pipelines

Remove infra-gate and infra-post; remove infra-check everywhere except
for project-config so that we can quickly iterate on it.

Enable the pipelines for all projects.

Move infra-check pipeline after check to have those related pipelines
displayed together.

This partially reverts I084b819ea0a4b67f36df61ccb3bfd6963cc3940d and
reverts Ieced5db4bb8a29eb494dffce3bed030a528f46a1 and
I5646ab81eb1a6515b32c42a2c3c4e64a94be4748.
