This change allows clients of the RegionAllocator to provide callbacks
that are invoked when regions are split or merged.
This will later be needed on Windows when a RegionAllocator is used to
manage a placeholder mapping as these need to be split and merged (using
the VirtualFree API) as well.

Code pages need to be swept on the main thread for now. Originally this
was done to prevent RWX on code pages, but there might be more other
smaller issues like the linked bug. Most likely this restriction isn't
a problem for concurrent SP at the moment, so stick with this
invariant for now.

The second method Heap::FreeSharedLinearAllocationAreas is used to free
all LABs in the shared heap for shared GCs and in the future also on

Posting compile tasks from the parser has several issues:

  1. We don't know how many functions there will be total, so we can't
     yet allocate shared_function_infos array on the Script
  2. Without this array, inner function compiles can't look up their own
     inner functions during bytecode finalization, so we can't run that
     finalization before script parse completes
  3. Scope analysis can't have run yet, so we can only post top-level
     function tasks and if we allocate SharedFunctionInfos early they
     are forced into a bit of a limbo state without an outer ScopeInfo.

Instead, we can post compile tasks during bytecode generation. Then, the
script parse is guaranteed to have completed, so we'll have a
shared_function_infos array and we will have allocated ScopeInfos
already. This also opens the door for posting tasks for compiling more
inner functions than just top-level, as well as generating better code
for functions/methods that reference same-script top-level
let/const/class.

With eager compilation, CompilationEventCallbacks get released when all
compilation units in the compilation state are finished. This is
possible because no future compilation event could get triggered after
that. With dynamic tiering, though, the {FinishedCompilationChunk} event
can trigger repeatedly, even after all compilation units finish at some
point in time, as dynamic tiering can create new CompilationUnits. As
a temporary fix, CompilationEventCallbacks don't get released when
dynamic tiering is enabled.

This CL fixes this issue by turning the callback from an std::function
into a class, and adding a second function to the class which indicates
whether the callback can be released when all compilation units in the
compilation state are finished. Thereby all callbacks can be deallocated
except the ones like the code caching callback which waits for the
{FinishedCompilationChunk} events.

In each wasm CallDescriptor, we store the signature of the call based on
the real parameters passed to the call. This signature is more precise
than the formal function signature. We use this signature in inlining
to enable more optimizations.

Changes:
- Add wasm_sig_ field to CallDescriptor.
- Construct the real signature in {DoCall} and {DoReturnCall} in
  graph-builder-interface, and pass it to all call-related functions in
  WasmGraphBuilder.
- Update {ReplaceTypeInCallDescriptorWith} to use ValueType over
  MachineType. Construct the updated function signature.
- In wasm-inlining, kill the Call node after inlining.
- Add two tests.
