[shared storage] Add Web Locks to the worklet
Explainer: WICG/shared-storage#199
Key points:
SharedStorageWorkletNavigatoris a new interface that only
supportslocks. Implementation-wise, we inherit NavigatorBase
so it's compatible with the LockManager implementation. Some
methods are obviously unreachable (e.g. GetAcceptLanguages()).- Add the member
LockManager<OriginLockGroupId> lock_manager_;to
SharedStorageWorkletHostManager: The locks have a shared storage
specific scope (separate from the Window/Worker locks), and are
further partitioned by shared storage origin.
