Abstract reference types in the fuzzer have only generated trivial
values. This CL adds the capability for them to generate values of their
subtypes in addition.
Drive-by: Fix emission of multiple tables in wasm-fuzzer-common.

This moves every single class/function out of include/v8.h into a
separate header in include/, which v8.h then includes so that
externally nothing appears to have changed.
Every include of v8.h from inside v8 has been changed to a more
fine-grained include.
Previously inline functions defined at the bottom of v8.h would call
private non-inline functions in the V8 class. Since that class is now
in v8-initialization.h and is rarely included (as that would create
dependency cycles), this is not possible and so those methods have been
moved out of the V8 class into the namespace v8::api_internal.
None of the previous files in include/ now #include v8.h, which means
if embedders were relying on this transitive dependency then it will
give compile failures.
v8-inspector.h does depend on v8-scripts.h for the time being to ensure
that Chrome continue to compile but that change will be reverted once
those transitive #includes in chrome are changed to include it directly.

This allows the compiler to eliminate more unneeded branches. Since all
functions just do a lookup in a static table (either directly, or via
compiling a switch to such a lookup), they are also good candidates for
inlining, which is made possible by this change.
One DCHECK is removed instead of pulling in the inl header, which would
require more refactoring since the check is in a non-inl header.

the heap) create more vectors on the stack, via initializer lists.
As this is "only" a fuzzer, performance is not really critical, but
still has some impact on the efficiency of the whole fuzzer.
That said, this CL is mostly a cleanup to replace unwanted code pattern
by better code.

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.

The reference types wasm proposal dropped all subtyping. Subsequently,
the 'anyref' type was renamed to externref.
This changes all references of the *type* anyref to externref.
Additionally, the flag that permits this extension is renamed to
"reftypes" to mirror the proposal name.

The proposal uses the lane shape, e.g. i64x2.anytrue, and we were using
s1x2.anytrue in our opcodes. This was a legacy naming, because we were
trying to bitpack the booleans. Now that we aren't doing that, rename
these to be more consistent with the proposal.
This was done with a straightforward sed script, changing both cpp code
and also some comments in mjsunit test files.

No regression test added because the generated JS file is not helpful

In https://crrev.com/c/2084321 I added s128 load store to the fuzzer,
and updated the memop generator to use IsPrefixOpcode check. But it was
used wrongly. IsPrefixOpcode checks a 1 byte opcode and see if it is a
prefix opcode, but if memory_op is already a 2 byte opcode, it will fail
the IsPrefixOpcode check.

This is still very limited, but we will have some simd instructions.
We add 2 kinds of instructions:
- any_true to generate i32 from v128
- add to generate v128 from v128 and v128
- extract_lane to generate v128 from all other types
We do not add v128 to the list of types returned by GetValueType, since
that is used in a couple of places, like generating globals, which
requires v128.const but is not implemented yet.
Special case to enable the experimental-wasm-simd flag since simd is not
included in wasm-staging yet.

already use kExprTableGet and kExprTableSet, but for locals and globals
we still use the old wording.
This renaming is mostly mechanical.
