Most function signatures are created once and never changed. Hence pass them as const pointer. This makes it clear in function signatures that these parameters will not be modified. This also avoids a few ugly const_casts where we were passing pointers to constexpr FunctionSigs via non-const pointers.

This adds static types to the argument class that accesss the arguments in the stack. kRuntime arguments are used by runtime functions and kJS arguments are used to access the JS stack (eg. builtins).

This is a first step to make {WasmCode} objects smaller. Many code offsets are currently stored in {size_t} even though there were originally (during assembly) an int. Others are stored in {uint32_t}. This CL switches the function index and all code lengths and offsets to int, because a) bigger code is not supported anyway, and b) the style guide recommends int over unsigned types. This makes the {WasmCode} 24 bytes smaller on x64 (from 144 to 120 bytes).

1) Instead of passing three boolean values to |TriggerCallbacks|, pass one EnumSet which contains all events to trigger. 2) Remember which events already happened, to avoid triggering them again. 3) Compute triggered events once after the loop in |OnFinishedUnits|, instead of checking for every finished unit. 4) When a new callback is registered, trigger all previous events immediately. This solves issue v8:10217. 5) Replace |NotifyTopTierReady| by |AddCallback| which is identical now. 6) Do not call |OnFinishedJSToWasmWrapperUnits| if no wrappers were compiled (this is a minor performance optimization; we save taking and releasing a lock). 7) Drive-by: Make the |EnumSet| constructor really constexpr (by making |Mask| constexpr).

The JSArrayBuffer::extension-field might not be aligned with pointer compression enabled. However on AArch64 pointers need to be aligned if you perform atomic operations on them. Therefore split extension into two 32-bit words that each get updated atomically. There is no ABA problem here since the extension field only transitions from NULL --> value --> NULL. After Detach(), Attach() isn't invoked anymore.
