- Rename FunctionLiteral::FunctionType to FunctionSyntaxKind.
- Re-express IsWrappedBit, IsDeclarationBit, IsAnonymousExpressionBit,
and IsNamedExpressionBit in SFI::flags as FunctionSyntaxKind. This
frees up 1 bit in SFI::flags.
- Re-express the analogous bits in ParseInfo as FunctionSyntaxKind.
- Simplifies some logic in the back-and-forth passing of this info
between SFI and ParseInfo.
- Drive-by fix parsing class member initializations as kAccessorOrMethod.

> [d8] Remove maximum workers limitation
>
> This CL refactors the lifetime management of the v8::Worker C++ object
> and in the process lifts the 100 maximum worker limitation. To do this,
> it uses a Managed<v8::Worker> heap object and attaches the managed to
> the API worker object.

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.
