podman rmi: refactor logic

While this commit was initially meant to fix #5847, it has turned into a
bigger refactoring which I did not manage to break into smaller pieces:

 * Fix #5847 by refactoring the image-removal logic.

 * Make the api handler for image-removal use the ABI code. This way,
   both (i.e., ABI and Tunnel) end up using the same code.  Achieving
   this code share required to move some code around to prevent circular
   dependencies.

 * Everything in pkg/api (excluding pkg/api/types) must now only be
   accessed from code using `ABISupport`.

 * Avoid imports from entities on handlers to prevent circular
   dependencies.

 * Move `podman system service` logic into `cmd` to prevent circular
   dependencies - it depends on pkg/api.

 * Also remove the build header from infra/abi files.  It will otherwise
   confuse swagger and other tools; errors we cannot fix as go doesn't
   expose a build-tag env variable.

Fixes: #5847
