Require V8 to be explicitly initialized before an Isolate is created
...
We also initialize the Isolate on creation.
This should allow for getting rid of the last remaining default isolate
traces. Also, it'll speed up several isolate related operations that no
longer require locks.
Embedders that relied on v8::Isolate to return an uninitialized Isolate
(so they can set ResourceConstraints for example, or set flags that
modify the way the isolate is created) should either do the setup before
creating the isolate, or use the recently added CreateParams to pass e.g.
ResourceConstraints.

Move configuration of ResourceConstraints to Isolate construction
...
We can only set resource constraints before the isolate is initialized.
Since in the future, we want to initialize isolates at construction
time, we need to set constraints there.
It's possible to later modify the stack limit, so introduce an
Isolate::SetStackLimit method for that.
The SetResourceConstraints method will be deprecated. Users should pass
ResourceConstraints to Isolate::New, and use Isolate::SetStackLimit to
later modify the stack limit.

Currently, a new isolate is created in an uninitialized state, and
...
several API methods will automatically initialize it. During this
uninitialized state, code event handlers and function entry handlers can
be attached to the isolate.
This CL deprecates SetFunctionEntryHook and moves the configuration of
those handlers to the Isolate factory method.
This will allow for initializing the Isolate at creation time in the
future.
Users of V8::SetFunctionEntryHook should pass the entry hook to
Isolate::New instead. V8::SetJitCodeEventHandler should either be passed
to Isolate::New as well, or (if startup events are not required) invoked
via the Isolate.

We go back to patching the code for lazy deoptimization because ICs need the on-stack return address to read/update the IC address/state.
The change also fixes bunch of tests, mostly by adding more deoptimization points.
(We still need to add code to ensure lazy deopt patching does not overwrite ICs and other lazy deopts; this is coming next.)

Reland
...
- "Switch inlining to use simplified instead of machine loads."
- "Add copy support in inliner."
Reland fixes:
- size_t conversion for 64bit arches
- Don't call front() on empty vector
(triggers assertion on windows)
- turbo_inlining now implies turbo_types, as
it requires simplified lowering.

Add script streaming API.
...
Blink will use this API to stream script data into V8 as the scripts
load. During loading, V8 can already parse the scripts. They will be then
compiled and executed when the loading is complete.
This is a reincarnation of https://codereview.chromium.org/366153002/
with fixes.
