This adds a new --experimental-value-unavailable flag, which is disabled for now. When enabled the debugger reports values that are optimized out by TurboFan and values of certain variables in Temporal Dead Zones (TDZ) as unavailable. Internally we use a special `value_unavailable` accessor info to represent these values, and on the debugger boundary we report these properties with `value`, `get`, or `set`.

Initial implementation for concurrent shared arrays. Current implementation exposes a `SharedArray` constructor, but its syntax might change in the future. Shared arrays can be shared across Isolates, have a fixed size, have no prototype, have no constructor, and can only store primitives, shared structs and other shared arrays. With this CL shared structs are also allowed to store shared arrays. The Backing storage for the SharedArrays is a `FixedArrayBase`. This CL introdces a new ElementKind: `SHARED_ARRAY_ELEMENTS`. The new kind should match the overall functionality of the `PACKED_SEALED_ELEMENTS` kind, but having it as standalone kind allows for easier branching in CSA and turbofan code.

Adds Module::GetStalledTopLevelAwaitMessage() API which searches for modules that have no pending async dependencies but have not yet resolved. An embedder may call this API when they are about to exit to check if TLA evaluation has stalled and provide a better error message.
