Post-only hooks

[adam-alchemy]

Motivation

The ERC-6900 standard does not prohibit post-only execution hooks and permitted call hooks. However, the RI only supported associated post exec hooks.

Solution

• Refactor execution hooks and permitted call hooks into a reusable HookGroup struct.
• Add support for post-only hooks during installation and uninstallation.
• Run post-only hooks during execution. This is achieved by adding them to the end of the array of PostExecToRun items.
• Fix a bug with pre-exec hooks running with incorrect calldata in executeFromPlugin.
  • This refactor unfortunately caused a stack-too-deep error in the non-IR build, so I also refactored _doPrePermittedCallHooks to take in the key to get back under the stack limit.
