* Define a generic allocator interface to enable static polymorphism for allocators (see `GenericAllocator` in `src/allocators.zig`). Note that `std.mem.Allocator` itself is considered a generic allocator. * Add utilities to `bun.allocators` for working with generic allocators. * Add a new namespace, `bun.memory`, with basic utilities for working with memory and objects (`create`, `destroy`, `initDefault`, `deinit`). * Add `bun.DefaultAllocator`, a zero-sized generic allocator type whose `allocator` method simply returns `bun.default_allocator`. * Implement the generic allocator interface in `AllocationScope` and `MimallocArena`. * Improve `bun.threading.GuardedValue` (now `bun.threading.Guarded`). * Improve `bun.safety.AllocPtr` (now `bun.safety.CheckedAllocator`).
