The interpreter is not used in production code any more, hence move it
from src/wasm to test/common/wasm.
It's still used in unit tests, cctests, and in fuzzers.
Because of this move, a few more methods had to be exported via
V8_EXPORT_PRIVATE.

This change enables automatic generation of Cast<> operators for
classes that are defined in Torque.
* Cast<> macros are generated for all classes that are defined in
Torque code that are neither shapes nor marked with a new
@doNotGenerateCast annotation.
* Implicitly generated Cast macros simply call through to an
internally-defined "DownCastForTorqueClass" macro that implements
the cast using one of three strategies for efficiency. If the class
has subclasses (i.e. a range of instance types including subtypes),
the DownCastForTorqueClass checks for inclusion in the instance type
range. If the class has a single instance type (i.e. no subclasses),
then either 1) a map check is used if the class has a globally-
defined map constant or 2) an equality check for the instance type
is used.
* Added new intrinsics to introspect class information, e.g. fetching
instance type ranges for a class, accessing the globally-defined map
for a class.
* Removed a whole pile of existing explicit Cast<> operators that are
no longer needed because of the implicitly generated Cast<> macros.
* Added tests for the new Cast<> implementations.

This is a reland of e0c1a349ea
The issue was passing SentinelPointer (== +1) through T*.
The fix is disabling cfi unrelated cast diagnostic for the bottlenecks
(Get()). This means that nullptr is treated the same as
kSentinelPointer.
The alternative would be a DCHECK that Get() does not return
kSentinelPointer and adjusting all Member and Persistent logic that
uses Get() to work on void*. This is quite intrusive as it involves
Swap(), heterogeneous assignments, comparisons, etc.

Motivation:
Changes to the typed function references and gc proposals solidified
the notion of heap type, clarified nullable vs. non-nullable reference
types, and introduced rtts, which contain an integer depth field in
addition to a heap type. This required us to overhaul our ValueType
representation, which results in extensive changes.
To keep this CL "small", we do not try to implement the binary encoding
as described in the proposals, but rather devise a simpler one of our
own (see below). Also, we do not try to implement additional
functionality for the new types.
Changes:
- Introduce HeapType. Move heap types from ValueType to HeapType.
- Introduce Nullability for reference types.
- Rework ValueType helper methods.
- Introduce rtts in ValueType with an integer depth field. Include depth
in the ValueType encoding.
- Make the constructor of ValueType private, instead expose static
functions which explicitly state what they create.
- Change every switch statement on ValueType::Kind. Sometimes, we need
nested switches.
- Introduce temporary constants in ValueTypeCode for nullable types,
use them for decoding.
- In WasmGlobalObject, split 'flags' into 'raw_type' and 'is_mutable'.
- Change IsSubtypeOfRef to IsSubtypeOfHeap and implement changes in
subtyping.
- kWasmFuncRef initializers are now non-nullable. Initializers are
only required to be subtypes of the declared global type.
- Change tests and fuzzers as needed.

... for nci code, in which several phases of the compiler are not
active:
LowerJSCreateCatchContext
LowerJSCreateEmptyLiteralObject
LowerJSCreateIterResultObject
LowerJSCreateWithContext
LowerJSGetIterator
LowerJSGetTemplateObject
With this change, the nci variant passes the test suite. Tests
relying on turbofan-specific behavior (e.g. deopts) are skipped.
