is not used in that file. Add missing includes in other files that

Since the compile job can always be reused after creation (even if it
runs out of work), we do not need the logic to (re-)initialize it. In
fact, it will always only be initialized once already.
This allows us to initialize it once during construction of the
compilation state (or right after the initialization), and then access
it without locks later.
In addition, this CL
1) renames "current_compile_job_" to "compile_job_", since there will
always only be one now;
2) removes the {ScheduleCompileJobForNewUnits} method, and just does a
{compile_job_->NotifyConcurrencyIncrease()} instead;
3) removes the {has_priority_} field and just directly does a
{compile_job_->UpdatePriority} call.
The streaming test platform needed to be fixed to avoid calling {Join}
on the job handle, which would invalidate the handle afterwards.
Instead, we just run all tasks as long as there are any.

Issue 1: WasmEngine UAF when CompilationState is destroyed
asynchronously
Fix: Include https://chromium-review.googlesource.com/c/v8/v8/+/2565508
in this CL. Use OperationBarrier to keep WasmEngine alive.
Issue 2: In gin, JobTask lifetime is not extended beyond
JobHandle, thus making CancelAndDetach unusable.
This is fixed in chromium here:

As part of an effort to prepare the Recorder interface for general use,
we had to make some changes to the way the existing Wasm Events are
being used. In particular,
- it is more fitting to use a ElapsedTimer than a TimedScope to
measure the durations in src/wasm/module-[decoder|instantiate].cc
- we want to rename the wall_clock_time_in_us field to duration_in_us
for clarity.
Because these Wasm events are already being instantiated in chromium,
renaming the field requires a two-step change. This is the first of
those changes.

the mock platform just before it is freed.
