The main changes of this CL are:

It should no longer be assumed that an empty ArrayBuffer has a nullptr
backing store. This is in preparation for the move to caged pointers,
which cannot represent nullptr, and will instead likely provide a
EmptyBackingStore constant pointing inside the virtual memory cage. For
that reason, a new JSArrayBuffer::IsEmpty() helper is introduced, which
should be used instead of checking against nullptr.

CodeStubAssembler::GetTypedArrayBuffer now checks for on-heap
TypedArrays instead of comparing the backing store pointer to nullptr.
This is consistent with the implementation in JSTypedArray::GetBuffer.

v8::ArrayBufferView::CopyContents now uses JSTypedArray::DataPtr instead
of relying on nullptr backing stores to handle on-heap TypedArrays.

The serializer and deserializer now check for IsEmpty() and use the
kEmptyBackingStoreRefSentinel value to serialize empty backing stores.

Empty ArrayBuffers allocated for on-heap TypedArrays now have a
byte_length of zero. This allows removing the allocation_length() (and
allocation_buffer()) methods, which were only (incorrectly, as they
don't account for GSABs) used for memory measurements.

Design doc: bit.ly/3jEVgzz

We separate the internal representation of function references in Wasm
from their JSFunction-based (external) representation. This improves
performance of call_ref by requiring less indirections to load the
context and call target from a function reference. In the boundary
between wasm and JS/the C API, we add transformations between the two
representations.

Detailed changes:
- Introduce WasmInternalFunction, containing fields required by
  call_ref, as well as a reference to the corresponding
  WasmExternalFunction. Add a reference to the WasmInternalFunction in
  WasmFunctionData. The {WasmInternalFunction::FromExternal} helper
  extracts the internal out of an external function.
- Change {WasmInstanceObject::external_functions()} to internal
  functions.
- Change wasm function tables to contain internal functions.
- Change the following code to use internal functions:
  - call_ref in liftoff and Turbofan
  - function type checks in liftoff and Turbofan
  - CallRefIC and GenericJSToWasmWrapper builtins
  - {InitExprInterface::RefFunc}
  - module-compiler.cc in {ProcessTypeFeedback}
  - In module-instantiate.cc, in function-rtt creation.
- Add transformations between internal and external functions in:
  - WasmWrapperGraphBuilder::{ToJS, BuildUnpackObjectWrapper, FromJS,
    BuildJSToJSWrapper}.
  - debug-wasm-objects.cc in {FunctionProxy::Get},
    {WasmValueObject::New} and {AddWasmTableObjectInternalProperties}.
  - runtime-wasm.cc in ReplaceWrapper
  - the C and JS APIs
  - module-instantiate.cc, in import and export processing, as well as
    {InitializeIndirectFunctionTables}
  - WasmTableObject::{IsValidElement, SetFunctionTableEntry}
  - {WasmGlobalObject::SetFuncRef}
- Simplify body descriptors of WasmExternalFunction variants.
- Adjust tests.

a general way to fix shadow whenever ASM_CODE_COMMENT is used, by
appending the current line, via __LINE__ macro to the variable name.
However, __LINE__ is not expended correctly when it is directly part of
a variable name.

To fix the shadowing, we use UNIQUE_IDENTIFIER to give unique names.

This CL improves --track-retaining-path with incremental marking:

* Retainers need to be cleared *after* the GC and for full GCs only.
  Otherwise a scavenger that runs during incremental marking would
  clear all retainers.
* Register marked root objects in IncrementalMarking::MarkRoots with
  retaining_root_.
