This CL introduces SideEffectDetectorScope which requires explicit
allowlisting of cases when side effects are allowed after calling
interceptor callbacks.
Side effects are not allowed when the callback does not intercept
the request.
The side effects detector is not enabled yet, it will be enabled in
a follow-up CL.

This moves every single class/function out of include/v8.h into a
separate header in include/, which v8.h then includes so that
externally nothing appears to have changed.
Every include of v8.h from inside v8 has been changed to a more
fine-grained include.
Previously inline functions defined at the bottom of v8.h would call
private non-inline functions in the V8 class. Since that class is now
in v8-initialization.h and is rarely included (as that would create
dependency cycles), this is not possible and so those methods have been
moved out of the V8 class into the namespace v8::api_internal.
None of the previous files in include/ now #include v8.h, which means
if embedders were relying on this transitive dependency then it will
give compile failures.
v8-inspector.h does depend on v8-scripts.h for the time being to ensure
that Chrome continue to compile but that change will be reverted once
those transitive #includes in chrome are changed to include it directly.

This is a speed-for-memory tradeoff, which can be achieved by
re-mapping the builtins code blob into existing code range.
This CL handles cases where both embedded and un-embedded off-heap
builtins' PCs might appear on the call stack.
The v8_enable_short_builtin_calls build flag is still disabled.

String::NewFromLiteral is a templated function that takes a char[N]
argument that can be used as an alternative to String::NewFromUtf8 and
returns a Local<String> rather than a MaybeLocal<String> reducing the
number of ToLocalChecked() or other checks.
Since the string length is known at compile time, it can statically
assert that the length is less than String::kMaxLength, which means that
it can never fail at runtime.
This also converts all found uses of NewFromUtf8 taking a string literal
or a variable initialized from a string literal to use the new API. In
some cases the types of stored string literals are changed from const
char* to const char[] to ensure the size is retained.
This API does introduce a small difference compared to NewFromUtf8. For
a case like "abc\0def", NewFromUtf8 (using length -1 to infer length)
would treat this as a 3 character string, whereas the new API will treat
it as a 7 character string.
As a drive-by fix, this also fixes all redundant uses of
v8::NewStringType::kNormal when passed to any of the String::New*
functions.

The "Address" type is V8's general-purpose type for manipulating memory
addresses. Per the C++ spec, pointer arithmetic and pointer comparisons
are undefined behavior except within the same array; since we generally
don't operate within a C++ array, our general-purpose type shouldn't be
a pointer type.

variables and for storing directly to the JSGlobalObject. In the latter
case the dispatcher also ensures that JSGlobalProxy is provided as
a receiver if a setter function has to be called.
Unlike StoreIC the calling convention for the StoreGlobalIC does not include
receiver.
