When an object either gets promoted or evacuated, old-to-shared slots
need to be recorded like we already do for old-to-old or old-to-new.

The jump table and far jump table are allocated once per code space, but
the lazy compile table only needs to exist exactly once, and it does not
really matter in which code space we allocate it.
Before dynamic tiering, we could always allocate it in the initial code
space (which was empty at the point when we allocated it), but with
deserialization of a partially tiered module we can end up in a
situation where we first deserialize some TurboFan functions into the
initial code space, and when we later try to allocate the lazy compile
table (when we encounter the first non-serialized function) we do not
have enough space any more in the initial code space.

This CL allows to allocate the lazy compile jump table in any code space
to avoid that failure.

This is a reland of commit 07e11a64.

The original change removed the fill_thehole_and_call_runtime bailout
in StringBuiltinsAssembler::StringToArray() so when the string
is external and cannot be unpacked, the FixedArray won't be filled
with holes before we call into the runtime, thus failing a
heap verification if a GC happens before the array is filled. This
reland adds back the bailout for this case.

If we grow memory (out-of-place, so only without trap handling and only
if the maximum is >1GB) and the previous size is close to the maximum,
then the minimum growth we calculate can be bigger than the allowed
maximum. In this situation, the {std::clamp} has undefined behaviour,
since the provided lower limit is bigger then the upper limit.

Thus apply {std::min} and {std::max} in an order such that {max_pages}
has precedence over {min_growth}.

So far all OLD_TO_SHARED slots were deleted after a shared GC. The
remembered set was rebuilt in the next shared GC from scratch. This CL
changes this behavior to only remove slots that don't point into the
shared heap anymore.

We still need to remove the full OLD_TO_SHARED slot set for young
generation pages though. During a shared GC we use the OLD_TO_SHARED
remembered set to cache references into the shared heap even for
pages in the young generation to avoid the second new space object
iteration.

The {LiftoffAssembler::Load} method already receives an {i64_offset}
parameter which skips the UXTW (zero extension of 32-bit addresses) in
the memory operand. The same needs to happen on stores.

On 32-bit platforms, we cannot have addresses >=4GB anyway (they would
be detected as OOB before reaching the point in question), so this is
not a problem. On x64, all 32-bit registers are zero-extended already
(which is debug-checked in the generated code), so this is also no
problem (and we just ignore the additional parameter).

Currently, we canonicalize types for call_indirect by looking in the
current module for a signature of the same shape. This is not enough
as of wasm-gc. Instead, the canonical identifier representing a type
has to be computed via isorecursive canonicalization.
This change is implemented behind a flag for now.
Future work: Also integrate export wrappers with isorecursive
canonical types. We need to store wrappers in instance-independent
storage.

Drive-by:
- Always emit type check for call_indirect. We did not emit a check
  only when typed-function-references was enabled, but not gc. This
  is not something that will be possible long-term.
- Fix some wasm cctests.
