This prepares a refactoring to add and publish compilation results in
batches. For this, we need to separate the two phases, so that we can
lock the module, allocate all the code space, release the lock, copy
the code, lock the module, publish the code, and release the lock
again.
In particular, this CL does the following:
1) It removes the {AddOwnedCode} method. The functionality of creating
the {WasmCode} and memcpy'ing the instruction into that is done in
the other {Add*Code} methods. Adding to {owned_code_} is done in
{PublishCode}.
2) {PublishInterpreterEntry} is now functionally equivalent to
{PublishCode}, so it's removed.
3) After {AddCode}, the caller has to call {PublishCode}. In a
follow-up CL, this will be called in batches (first {AddCode} them
all, then {PublishCode} them all).
4) {AddCompiledCode} now assumes that the {WasmCompilationResult}
succeeded. Otherwise, the caller should directly call {SetError} on
the {CompilationState}.
5) {PublishCode} is now the chokepoint for installing code to the code
table, the owned code vector, the jump table, and setting interpreter
redirections. It replaces previous direct calls to {InstallCode} or
explicitly adding to {owned_code_}.
6) Increasing the {generated_code_size_} counter is now done in
{AllocateForCode}, which is the chokepoint for allocating space for
generated code. This way, we will only increase this counter once
once we allocate in batches.
