Refactor - Merges BuiltinPrograms into LoadedPrograms

[Lichtso]

Problem

Continuation of #31565.
Built-in programs should take the same paths through the program-runtime as user supplied programs do. This is an important step for their ongoing unification in program-runtime-v2.

Summary of Changes

• Replaces the functions genesis_builtins() and builtin_feature_transitions() with a static slice BUILTINS
• Replaces BuiltinFeatureTransition with BuiltinPrototype which has an optional Pubkey for the activation feature, the value None signals a built-in to be present at genesis
• Removes builtins::create_builtin(), use loaded_programs::LoadedProgram::new_builtin() instead
• Removes BuiltinPrograms, Bank::builtin_programs and InvokeContext::builtin_programs
• Removes with_mock_invoke_context_and_builtin_programs!()
• Fetches built-ins from InvokeContext::programs_loaded_for_tx_batch instead of InvokeContext::builtin_programs
• Switches from linear search to constant time hash map lookup for dispatching built-in programs
• Sets LoadedProgram::account_size to name.len() for built-ins
• Sets effective_slot and deployment_slot to the slot in which their feature was activated
