It is better to infer the language mode from the context and the closure instead of getting it from the feedback vector. This will allow us to use some of these builtins even when feedback vectors are not allocated. Language mode is only needed to decide if we need to throw an exception when a store fails. This is on a slow path and hence deriving the language mode is not on critical path.

Anyref parameters can exist across GC runs. Therefore the GC has to know where anyref parameters are on the stack so that it can mark them in its marking phase, and update them in the compaction phase. Already in a previous CL we grouped all anyref parameters so that they can be found more easily in a stack frame, see https://crrev.com/c/1371827. In this CL we implement the stack scanning itself. Note that anyref parameters are not scanned while iterating over the caller's frame (to which they actually belong), but while iterating over the callee's frame. The reason is that with tail-calls, only the callee knows how many tagged stack parameters (aka anyref parameters) there are.

Inferring the language mode involves iterating the stack to find the closure. This is an expensive operation and should be done only when required. This cl changes the implementation to infer the language mode only when we can't defer it any further. Currently, we infer the language mode when throwing an exception or when passing this information to PropertyCallbackArguments. This cl also changes the language mode parameter to SetProperty related methods to Maybe<ShouldThrow>. We only use the language mode to decide if we need to throw and using ShouldThrow instead of language mode simplifies the code by avoiding conversions from Maybe<ShouldThrow> to Maybe<LanguageMode> and vice-versa.

The WasmCodeManager held a list of all Isolates that use the WasmEngine/WasmCodeManager (those two are 1:1). Since we want to move all isolate-specific tasks (like code logging and compilation callbacks) to the WasmEngine, this CL moves this management from the WasmCodeManager to the WasmEngine. We now have a bidirectional mapping from NativeModules to the Isolates that use them, and from an Isolate to all the NativeModules it uses (n:n). The IsolateData struct will be extended in follow-up CLs to hold things like the ForegroundTaskRunner. The Isolate* in the NativeModule / CompilationState will eventually be removed.

Declare Variables with a name and position, rather than by passing through a VariableProxy. This allows us to not create dummy proxies for things like function declarations, and allows us to consider those declarations unused. As a side-effect, we also have to check if a variable is unused in the bytecode generator (as it will no longer be allocated), and we end up skip generating code/SFIs for dead variables/functions.
