Change the unittest runner to no longer uncondtionally set up a default
platform in the "environment", but to instead make platform set-up part
of the "mixin" framework for test fixtures.
Requires modifying some tests that expect the platform to be available,
and all flag implications resolved, before the mixin constructors run.
We still keep the environment for setting up the process for cppgc. This
process setup can only be done once per process, so it can no longer use
the platform -- that's ok though, the page allocator used by cppgc's
process initialisation doesn't have to be the same as the platform's so
we can just pass in a separate new one.

Rather than requiring the user of a LocalIsolate to pass in a
RuntimeCallStats from a WorkerThreadRuntimeCallStatsScope, create the
scope in the LocalIsolate directly and use its RuntimeCallStats in the
LocalIsolate constructor.
We can't do this for the main thread LocalIsolate, since
WorkerThreadRuntimeCallStatsScope doesn't work on the main thread, so
there we use the main-thread RuntimeCallStats instead.
This flushes out some issues of background-thread LocalIsolates being
used on the main thread, so fix those too, as well as RCS scopes using
background counters for operations that could happen on the main thread.

Introduce a ReusableUnoptimizedCompileState class, passed to ParseInfo,
which stores a couple of pointers and most importantly the Zone and
AstValueFactory of the parse. This allows the Zone and AstValueFactory
to be reused across multiple parses, rather than re-initialising
per-Parse.
With this, we can amend the LazyCompileDispatcher to initialise one
LocalIsolate, Zone and AstValueFactory per background thread loop,
rather than one per compile task, which allows us to reduce per-task
costs and re-use the AstValueFactory's string table and previous String
internalizations.

Rather than creating a ParseInfo when creating a BackgroundCompileTask
(and passing ownership across to the BG thread which deallocates it),
create one when running it.
This allows the ParseInfo Zone to be both allocated and deallocated on
the same thread, which will improve its allocator friendliness.
As a side-effect, we now use the on-heap PreparseData from the
SharedFunctionInfo, rather than cloning the in-Zone PreparseData. This
means that we don't have to copy the PreparseData across Zones, but we
do need to Unpark the LocalHeap when accessing preparse data.

Add suppose for compiling non-eager, non-top-level inner functions in
parallel, using the compiler dispatcher. This behaviour can be enabled
with --parallel-compile-tasks-for-lazy.
There are a couple of consequences:
* To support this we need support for off-thread ScopeInfo
deserialization, so this adds that too.
* The previous --parallel-compile-tasks flag is renamed to the more
descriptive --parallel-compile-tasks-for-eager-toplevel.
* Both parallel-compile-tasks flags are moved onto
UnoptimizedCompileFlags so that they can be enabled/disabled on a
per-compile basis (e.g. enabled for streaming, disabled for
re-parsing).
* asm.js compilations can now happen without an active Context (in
the compiler dispatcher's idle finalization) so we can't get a
ContextId for metric reporting; we'd need to somehow fix this if we
wanted asm.js UKM but for now it's probably fine.
* Took the opportunity to clean up some of the "can preparse" logic in
the parser.

Posting compile tasks from the parser has several issues:
1. We don't know how many functions there will be total, so we can't
yet allocate shared_function_infos array on the Script
2. Without this array, inner function compiles can't look up their own
inner functions during bytecode finalization, so we can't run that
finalization before script parse completes
3. Scope analysis can't have run yet, so we can only post top-level
function tasks and if we allocate SharedFunctionInfos early they
are forced into a bit of a limbo state without an outer ScopeInfo.
Instead, we can post compile tasks during bytecode generation. Then, the
script parse is guaranteed to have completed, so we'll have a
shared_function_infos array and we will have allocated ScopeInfos
already. This also opens the door for posting tasks for compiling more
inner functions than just top-level, as well as generating better code
for functions/methods that reference same-script top-level
let/const/class.

Remove the concept of JobId from LazyCompileDispatcher, and make SFIs
the canonical id for these jobs.
This has several consequences:
* We no longer split enqueing a job and registering a SFI with that
job. We did this previously because we could not allocate SFIs in
the Parser -- now with LocalHeap we can, so we do.
* We remove the separate Job vector, and make the SFI IdentityMap
hold pointers to Jobs directly. This requires a small amount of
extra care to deallocate Jobs when removing them from the map,
but it means not having to allocate new global handles for jobs.
* The SFI is passed into the BackgroundCompileTask instead of the
script, so our task finalization doesn't need the SFI anymore.
* We no longer need to iterate ParallelTasks after compiling (to
register SFIs), so we can get rid of ParallelTasks entirely and
access the dispatcher directly from the parser.
There are a few drive-bys since we're touching this code:
* Jobs are move to have a "state" variable rather than a collection
of bools, for stricter DCHECKing.
* There's no longer a set of "currently running" jobs, since this
was only used to check if a job is running, we can instead inspect
the job's state directly.

Calling FindIndexInScript performs a linear search on the script functions and can
take considerable time. With Bytecode flushing we will lose the function_literal_id
and have to call FindIndexInScript if we ever recompile the flushed function. This
can take a significant proportion of the recompilation time and has caused regressions
in rendering times for some web applications (e.g, 395ms in FindIndexInScript for 132ms
spent lazily re-compiling code).
To avoid this, add function_literal_id back into the SFI and remove it from
UnoptimizedCompileInfo. This will slightly regress memory usage (particularly
in cases where many of the SFIs are compiled), however it means we can remove
the FindIndexInScript function and avoid these long-tail regressions when
bytecode is flushed.

Avoid the linear lookup of function literal id when getting the shared
function info TraceID, by optionally passing through a FunctionLiteral.
Additionally, use the FunctionLiteralId helper when a FunctionLiteral is
not available, since it can also fast-path in some cases.
As a drive-by, allow using a ScriptIterator without an Isolate pointer
(e.g. manually creating a handle) to allow calling FunctionLiteralId
without an Isolate pointer.
