This moves the entire code generation phase (including code emission
into the native module) into the background task. The code manager is
fully thread safe by now and there are no Isolate-bound steps anymore.
The only step remaining on the foreground task is publishing the fully
finished code to other threads via {NativeModule::PublishCode}.

We currently store the protected instructions per code object in a
{std::unique_ptr<std::vector<ProtectedInstructionData>>}. This wastes
memory, because it requires two heap allocations, plus the vector might
over-allocate (and it currently does, because it is filled dynamically
during compilation).
This CL changes that to store the protected instructions in an
{OwnedVector}. This requires one copy after generating the list of
{ProtectedInstructionData} in an {std::vector} during compilation, but
saves memory afterwards.

Linkage-related methods were declared in wasm-compiler.h and
implemented in wasm-linkage.cc. This required all users of e.g. wasm
call descriptors to include the whole wasm compiler header. Also, some
wasm linkage information is independent of turbofan and also used
outside of the compiler directory.
This CL splits off wasm-linkage.h (with minimal includes) and puts it
in src/wasm. This allows to use that information without including
compiler headers (will clean up several uses in follow-up CLs).

This refactoring is a big step towards separating Turbofan-related code
from backend independent code. This will allow us to include way less
headers from "src/compiler" at various places.
The {WasmCompilationUnit} contained information for Turbofan
compilation, and for Liftoff compilation. This CL tears this apart, such
that {WasmCompilationUnit} holds backend-independent information, plus
a pointer to either {LiftoffCompilationUnit} or
{TurbofanWasmCompilationUnit}. These pointers are opaque, so that
{function-compiler.h}, defining {WasmCompilationUnit}, does not need to
include any Turbofan specific or Liftoff specific headers.

The previous code assumed that trap handling was a global concept, defined
by function trap_handler::UseTrapHandler(). This CL does the first step
in changing the decision to be specifiable at a module level.
Therefore trap_handler::UseTrapHandler() is replaced by
trap_handler::IsTrapHandlerEnabled(), and communicates if compilation
supports the use of trap handlers (but still allowing the use of
bounds checking on memory accesses).
It then refactors the classes ModuleEnv and WasmCompiledModule to have
a field "use_trap_handler" that specifies if traps should be used for
the memory accesses in the module being compiled.

By adding a per test source file namespace, we can avoid a lot of
symbol collisions in jumbo builds.
While we're at it, let's remove some "using" statements that also
cause trouble.

This fixes a few leftovers where we use WASM_EXEC_TEST, but then
unconditionally execute the compiled code, and also changes more tests
to use WASM_EXEC_TEST, hence run in both the interpreter and compiled
code.
Once we have land the baseline compiler, those tests will also execute
in baseline compilation mode.

We were using a boolean before, which makes the meaning non-obvious
when passed as a parameter. With the enum, you actually have to use
{kRuntimeExceptionSupport} or {kNoRuntimeExceptionSupport}.

This required splitting wasm-run-utils.h in header and implementation,
since the anonymous namespace in wasm-run-utils.h is now gone.
This is a reasonable refactoring in itself.

After the FallThruTo in kExprEnd, the current block {c} is never
unreachable. Hence, the check for {c->unreachable} afterwards can be
removed.
In the loop case, the {TypeCheckFallThru} already adds entries for
non-existing values to the stack, so no need to {PushEndValues}.
Also, add more tests for the loop case.
