Changes made in v6:
- Added `unpinned_new` constructor for `WwClass` and updated global macros.
- Changed all tests (and docs) to use Arc/KBox instead of `stack_pin_init`
for `WwMutex` and `WwAcquireCtx`.
- Added `LockKind` and `lock_common` helper to unify locking logic.
- Added context-based and context-free locking functions for `WwMutex`.
- Added `ww_mutex/exec` module, a high-level API with auto `EDEADLK`
handling mechanism.
