Instead of creating temporary {std::vector}s (which always allocate on
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.

Remove error reporting from parsing::Parse*, since in most cases we
didn't actually want them (clear errors afterward), and there was an
issue where Compiler::Compile would try to report errors already
reported in ParseAny, which ended up triggering unreachable code.
As a drive-by, move some one-off parse exception handling in
test-parsing into a CHECKED_PARSE_PROGRAM macro which replaces all the
"necessarily positive" calls to parsing::ParseProgram.

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.

The serializer currently cannot handle a heap state containing
arbitrary compiled Code objects. As a quick fix for the
--stress-snapshot d8 flag, we clear compiled data from the isolate
prior to the serialize-deserialize-verify pass.
With this change, mjsunit tests pass on x64.
The %SerializeDeserializeNow() runtime function would require more
work, since it is not possible to mutate the heap to this extent while
still preserving a runnable host context and isolate. We will need
another solution there.
Drive-by: Skip the stress_snapshot variant except for the mjsunit
suite.

Move the persistent compilation state and Isolate inputs (such as the
allocator, shared AST constants, hash seed, logger, etc.) which survives
across both parse and compile, out of ParseInfo and into a new
UnoptimizedCompileState class. Also add UnoptimizedCompilePerThreadState
for per-thread state such as stack limit and RCS.
In particular, this new state survives the ParseInfo being destructed,
which means it is available after off-thread finalization. This allows a
followup to access the PendingCompilationErrorHandler after finalization
and report errors on merge.

This is a reland of d91679bf3a
This reland adds initializers for the output flags.

UnoptimizedCompileFlags defines the input flags shared between parse and
compile (currently parse-only). It is set initially with some values, and
is immutable after being passed to ParseInfo (ParseInfo still has getters
for the fields, but no setters).
Since a few of the existing flags were output flags, ParseInfo now has a
new output_flags field, which will eventually migrate to a ParseOutputs
structure.

s128.store should be in the list for generating kStmt, not kWasmS128.
No regression test added because the generated JS file is not helpful
for this bug - the failed assertion is in the fuzzer, not the engine.
