As Wasm module can live longer than the isolate that initially created
them, it generally makes sense to use the WasmEngine's accounting
allocator for the decoded WasmModule.
Instead of passing that allocator through many functions, we can just
get it directly from the one global WasmEngine when we need it.

1) Pass {WasmFeatures} by value, it's a single word.
2) Pass a {base::Vector} instead of {start} and {end} pair.
3) Remove a redundant constructor (just pass an empty wire bytes vector
instead).

There are two flag updates from the Wasm C-API. Both are unnecessary:
FLAG_expose_gc is not needed because we call the internal API for
garbage collection; this is always allowed.
FLAG_experimental_wasm_eh is enabled by default, so does not need to be
set to true in that test.

The WasmEngine is shared across the whole process, so there is no need
to store it in every Isolate.
Instead, we can just get it from everywhere on any thread using
{wasm::GetWasmEngine()}, which is a simple read of a global.

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!'

With the upcoming "exception handling" proposal, we have to ensure
that traps are not catchable. This patch adds missing "uncatchable"
annotations to traps in the C-API and table-related instructions.

CreateFrameFromInternal always creates StackFrame from the frame at the index zero,
which is fine for the usage in Trap::origin, but is a bug for Trap::trace

Make WasmFeatures a proper class which uses an EnumSet under the hood.
This way, it inherits all behaviour of EnumSet like comparison, merge,
etc.
Accesses change from being simple field access into the struct to
actually bit tests in the EnumSet.

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.
