According to the latest changes in wasm-gc, externref will be renamed
to anyref, and will be assigned as the top of the reference type
hierarchy. Since in the current wasm type system funcref is not a
subtype of anyref, subtyping is now dependent on whether wasm-gc is
enabled.

WasmModuleBuilder is a class that is used to build Wasm modules in the
asm.js parser, in the fuzzer, as well as some tests. When it comes to
Wasm tables, WasmModuleBuilder currently supports only basic tables
(before the reftypes proposal) using an ad-hoc indirect-function index
vector.
This CL adds proper support for element sections and tables that use
them in the full potential of the reftypes extension. The new
functionality will only be used in the fuzzer and potentially some tests
in the future. Along this, we drop some functionality from
WasmModuleBuilder that was only used in tests and is redundant with the
new architecture.
Additionally, we remove tables other than externref and funcref from the
fuzzer (which were not supported properly or used anyway). We will
reintroduce them at a later time.

The adding of base:: was mostly prepared using git grep and sed:
git grep -l <pattern> | grep -v base/vector.h | \
xargs sed -i 's/\b<pattern>\b/base::<pattern>/
with lots of manual clean-ups due to the resulting
v8::internal::base::Vectors.
#includes were fixed using:
git grep -l "src/utils/vector.h" | \
axargs sed -i 's!src/utils/vector.h!src/base/vector.h!'

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.

This change is very mechanical:
own<Foo*> → own<Foo>
vec<Foo*> → ownvec<Foo>
As usual, everything in third_party/ is straight-up copied from upstream.
