All standard containers provide a method named {empty} to check whether
the container is empty. On {base::Vector}, that method is named
{is_empty}, while {empty} is an unused factory method for creating an
empty {Vector}.
This CL renames {is_empty} to {empty} and removes the unused factory
method.

This CL adds all the necessary {WasmCodeRefScope}s in the code base, or
at least a good approximation. A follow-up CL will enable a check that
a {WasmCodeRefScope} exists whenever a pointer to a {WasmCode} object
is returned from the {NativeModule}. This should flush out any missing
scopes.

We need to ensure that the NativeModule stays alive while any
{BackgroundCompileScope} exists, because during that time we hold
shared ownership of the mutex in the {BackgroundCompileToken}. If the
{NativeModule} dies during that period, we would need to get exclusive
ownership of the mutex and deadlock.
This change requires holding a {std::weak_ptr<NativeModule>} in the
BackgroundCompileToken instead of a raw pointer, hence it can only be
initialized after the NativeModule was created. This is done via a
separate {InitCompilationState} method.

The WasmCodeManager held a list of all Isolates that use the
WasmEngine/WasmCodeManager (those two are 1:1).
Since we want to move all isolate-specific tasks (like code logging and
compilation callbacks) to the WasmEngine, this CL moves this management
from the WasmCodeManager to the WasmEngine. We now have a bidirectional
mapping from NativeModules to the Isolates that use them, and from an
Isolate to all the NativeModules it uses (n:n).
The IsolateData struct will be extended in follow-up CLs to hold things
like the ForegroundTaskRunner. The Isolate* in the NativeModule /
CompilationState will eventually be removed.

This also makes the {AddCodeCopy} method more specific to only apply to
import wrappers, otherwise the use of {set_code} would be unprotected.

The problem was that in AsyncCompileJob::FinishModule we allocate a
handle, but when this function is called from streaming compilation, then
there was no HandleScope around AsyncCompileJob::FinishModule. This issue
was fixed in another CL, https://crrev.com/c/1172357. This CL is just a
rebase of the original CL.

This CL introduces a set of configuration options implemented as
a struct of booleans that together comprise the set of enabled
or detected features. The configuration options replace command-line
flags that were checked deep in the implementation. As such, it is
necessary to plumb them through multiple levels of abstraction.

In Liftoff, bugs often happen only if specific cache states are
constructed. For this, longer sequences of instructions are needed.
Thus, add a few rules to increase the chance of generating longer
sequences.

Stack parameters on arm64 require padding. Since the stack areas for
parameters and returns should not overlap, we have to pad the parameters
already during the construction of the CallDescriptor so that we can set
the correct stack offset for returns.
