Changes:
- Remove subtyping checks from value-type.h and move them to dedicated
files. Leave a limited version in value-type.h for testing.
- Implement subtyping for struct and array types, according to the
wasm-gc proposal.
- Implement type equivalence checking.
- Introduce a subtyping relation cache in WasmModule.
- Rename IsSubTypeOf -> IsSubtypeOf.
- Fix v8 possible bug where iterator_range took two unused type
parameters.
- Add unittests for subtyping.

In production, we will always pass a pointer to the decoded module. The
only reason for the existance of the nullptr checks is that tests
sometimes don't pass a module here. Hence we pay in production code for
a test-only feature.
This CL fixes this by always passing a module pointer from the decoder
tests. This even simplifies the code a lot by removing redundant code.
The {TestModuleBuilder} class was moved before the definitions of the
{FunctionBodyDecoderTest} class in order to be able to reuse it there.
It's unmodified otherwise.

Changes:
Cleanup:
- Make sure read_value_type has the same interface as other
read_* functions, i.e., returns the decoded value and writes
the consumed length into a pointer.
- DecodeLocals is now an instance method.
- DecodeLocals should fail when given a wrong number of locals.
Add tests to catch that.
- Fix a buggy test.
Refactoring in preparation of introducing the 'let'
instruction as per [wasm-gc]:
- DecodeLocals does not consume any input and can start from any pc.
- DecodeLocals gives the option of not appending the decoded
locals to local_types_.
- Separate locals initialization from signature.

There were three versions of type decoding for wasm in the codebase.
Not all of them decoded gc types with immediates (reference types)
correctly.

- Refactor the wasm binary decoder for unify type decoding.
- Update BranchTypeImmediate and SelectTypeImmediate to handle

SIMD opcodes consist of the prefix byte, then an LEB128 encoded int. We
were decoding this incorrectly as a fixed uint8. This fixes the decoder
to properly handle multi bytes.
In some cases, the multi byte logic is applied to all prefixed opcodes.
This is not a problem, since for values < 0x80, the LEB encoding is a
single byte, and decodes to the same int. If the prefix opcode has
instructions with index >= 0x80, it would be required to be LEB128
encoded anyway.
There are a bunch of trivial changes to test-run-wasm-simd, to change
the macro from BUILD to BUILD_V, the former only works for single byte
opcodes, the latter is a new template-based macro that correct handles
multi-byte opcodes. The only unchanged test is the shuffle fuzzer test,
which builds its own sequence of bytes without using the BUILD macro.

Fix a TODO from Ben to change the macro argument order to match the

macros and implement them via a common variadic macro.
Also, rename {WASM_CALL_INDIRECT_TABLE0} to {WASM_CALL_INDIRECT_TABLE}.
The name was confusing, because this macro explictly allows to set a
table index different from 0. Thus, just drop the "0" in the name.
The individual test changes were done via a vim macro, to avoid manual

> With this CL it is possible to use any anyfunc table in call-indirect,
> not just the first table.
>
> The current implementation is based on runtime calls. This is just an
> initial implementation which should be replaced by a
> dispatch-table-based eventually. However, this implementation allows
> us to move forward with the anyref proposal implementation.

With this CL it is possible to use any anyfunc table in call-indirect,
not just the first table.
The current implementation is based on runtime calls. This is just an
initial implementation which should be replaced by a
dispatch-table-based eventually. However, this implementation allows
us to move forward with the anyref proposal implementation.

This removes another two macros and introduces a templatized function
instead.
Note that there is only one instantiation per input length, not per
input.

This removes most macros from the function body decoder unittest. It
makes the {Validate} method (and the new {ExpectValidates} and
{ExpectFailure}) templates, to receive the code in different formats.
Drive-by: Rename "verify" to "validate".
