We move js-to-wasm wrappers to a WeakFixedArray in the isolate,
indexed by their canonical type index. This ensures that they are
reused across instances, and get GC'd when no longer needed.
We also remove eager compilation of wrappers.
This CL fixes some issues that were caused by out-of-bounds accesses
to wrapper arrays attached to module objects.

The number of feedback vector slots is currently stored in the
{WasmFunction}, returned in the {WasmCompilationResult}, and implicitly
stored as the size of the {call_targets} vector in
{FunctionTypeFeedback}.
This CL uses the latter as the source of truth, encapsulated in a new
{NumFeedbackSlots} function. This can be updated when adding new kinds
of feedback that need additional slots.
For now, the implementation of {NumFeedbackSlots} requires taking a
mutex, which we can hopefully avoid when productionizing speculative
inlining. We also take the mutex on every Liftoff compilation, which
adds synchronization between concurrent compilation which we previously
tried very hard to avoid (because it introduced significant overhead for
eager compilation).
As a nice side-effect, this CL reduces the per-function overhead by 8
bytes, independent of enabled features.

The split is rudimental and now is not needed at all:
- as part of the shared-cage effort we added HeapHandle pointer to the
BasePageHandle class (on the API side);
- for the value-full barrier we get HeapHandle from bitmasking the
value;
- for the value-less barrier we get it from the callback provided by the
caller.
The CL entirely removes the split and uses the single
BoundedPageAllocator. A minor note: the conservative stack scanning can
become sligthly more expensive.

Inner pointer resolution, to be used in conservative stack scanning,
assumes that all pages registered with the memory allocator are
iterable. Until this CL, this was not the case for pages that were
owned by the young generation semispaces but were unused. Such pages
are either in the "from" semispace, or in the "to" semispace but have
not yet been used.
This CL ensures that all pages owned by the young generation are iterable. It also adds tests to verify that inner pointer resolution
works correctly for unused young pages and for pointers above the
page area.

A couple of customers have asked about using devtools to get information
about temporary allocations, with the goal of reducing GC time and/or
peak memory usage. Currently, the sampling heap profiler reports only
objects which are still alive at the end of the profiling session. In
this change, I propose adding configuration options when starting the
sampling heap profiler so that it can optionally include information
about objects which were discarded by the GC before the end of the
profiling session. A user could run the sampling heap profiler in
several different modes depending on their goals:
1. To find memory leaks or determine which functions contribute most to
steady-state memory consumption, the current default mode is best.
2. To find functions which cause large temporary memory spikes or large
GC pauses, the user can request data about both live objects and
those collected by major GC.
3. To tune for minimal GC activity in latency-sensitive applications
like real-time audio processing, the user can request data about
every allocation, including objects collected by major or minor GC.
4. I'm not sure why anybody would want data about objects collected by
minor GC and not objects collected by major GC, but it's also a valid
flags combination.

Use Script as the key for the template object cache, instead of the
SharedFunctionInfo. This is because SharedFunctionInfos can be garbage
collected and then later recompiled, which would mean that we break the
spec's expectation that the template object stays constant.
Now the association of cached template object with SharedFunctionInfo is
via the function_literal_id of the SharedFunctionInfo, stored on the
CachedTemplateObject. These are linearly searched, similar to the linear
search over slot ids.
