refactor: clean up permisionless factory

[AustinGreen]

Motivation:

This is a cleanup PR that addresses feedback received during the permissionless factory refactor.

Modifications:

• Refactor core and policy config to use less memory
• Create _computePermissionId internal function in utils
• Add check that precomputed bootstrap strategy was authorized after strategies are deployed
• Replace config.deployer in policy salt with 0 and remove deployer param from LlamaCoreInitializationConfig struct
• Remove llamaCount from factory
• Add caller/msg.sender to the LlamaInstanceCreated event
• Move metadata tests to separate test file
  • Note in most cases we're indirectly testing the metadata through the policy.
• Create a comment in llama test setup explaining that root instance != privileged security access
• Remove unused imports in the src directory

Result:

Closes https://github.com/llamaxyz/llama/issues/429
