Load current Memory start/size off of the wasm instance when entering fast calls, so they can use that info for whatever they need to do. Fast calls from JS set the memory to null, and the memory does not need to be piped from wasm to slow callbacks as wasm always calls the fast function.

To make an array from a string, we were passing an interior pointer to the array's contents to NewStringFromUtf8 -- but the allocation could cause that interior pointer to become invalid. As part of the fix, also start to refactor to put the notion of UTF-8 variants closer to unibrow. This will allow us to unify more UTF-8/WTF-8/sloppy UTF-8 code paths.

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`.
