Refactors the CompilerDispatcher to be able to enqueue eager inner functions
for off-thread compilation during top-level compilation of a script.
Unoptimized compile jobs are simplified to only have two phases - compile
and finalization. Only finalization requires heap access (and therefore
needs to be run on the main thread). The change also introduces a requirement
to register a SFI with a given compile job after that job is posted, this
is due to the fact that an SFI won't necessarily exist at the point the job
is posted, but is created later when top-level compile is being finalized.
Logic in the compile dispatcher is update to deal with the fact that a job
may not be able to progress if it doesn't yet have an associated SFI
registered with it.

Merge the outer_scope_info and feedback_metadata fields on
SharedFunctionInfo. outer_scope_info is only used during parsing,
and feedback_metadata is only available after compilation, so the
two never exist at the same time. Thus, they can share a field slot.
The exception is un-compiling and re-compiling a function, where we
need the outer_scope_info again. Fortunately, the outer_scope_info
can be re-calculated from the SFI's scope_info.

needed for unoptimized compilation and optimized compilation. As a result, it is
cleaner to split up the CompilationInfo into UnoptimizedCompilationInfo and
OptimizedCompilationInfo.
Doing so also necessitate splitting up CompilationJob into UnoptimizedCompilationJob
and OptimizedCompilationJob - again there is not much overlap so this seems cleaner.

Follow-up to https://chromium-review.googlesource.com/c/v8/v8/+/941442.
"background" refers to a priority and is inappropriate to refer to
worker threads as many tasks posted to worker threads by v8 are in
fact high priority.
Also took advantage of this rename to make NumberOfWorkerThreads()
return an int instead of size_t. While it is never negative, int is
simpler and Google C++ style guide states to avoid unsigned integers in
such cases (ref. "On Unsigned Integers" @
https://google.github.io/styleguide/cppguide.html#Integer_Types).
The Chromium embedder for that call provided an int which was converted
to size_t for this override and most often casted back down to int on the
v8 side, adding churn, and readability overhead.

Expressions of the form
a_0 + a_1 + a_2 + a_3 + ... + a_n
seem to be reasonably common for cases such as building templates.
However, parsing these expressions results in a n-deep expression tree:
...
/
+
/ \
+ a_2
/ \
a_0 a_1
Traversing this tree during compilation can cause a stack overflow when n is
large.
Instead, for left-associate operations such as add, we now build up an
n-ary node in the parse tree, of the form
n-ary +
/ | \
/ | ... \
a_0 a_1 a_n
The bytecode compiler can now iterate through the child expressions
rather than recursing.
This patch only supports arithmetic operations -- subsequent patches
will enable the same optimization for logical tests and comma
expressions.

Since we don't have a full-codegen compiler anymore, we no longer
generate Code::FUNCTION kind. Nice! Here is some cleanup.

To enable executing code in a context of a particular time or date (e.g. when
codepath depends on whether it's say evening or New Year) there is a need for
a way to provide it bypassing actual system time.

Parse tasks are not currently used, and will need to be changed significantly
for background compilation, so we remove them for now.

This is in preparation to the removal of the FullCodeGenerator, we no
longer need the ability to stress the underlying implementation.

Don't hold a pointer to parse_info in compilation_info, and instead explicitly
add the fields needed in compiation_info. The intention is to make ParseInfo
only actually needed for parsing, and eventually make it possible to compile
with only a CompileInfo.
