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.

Since we switched to C++14 now, we can use {std::make_unique} instead
of our own {base::make_unique} from {template-utils.h}.

This replaces all typedefs that define types and not functions by the
equivalent "using" declaration.
This was done mostly automatically using this command:
ag -l '\btypedef\b' src test | xargs -L1 \
perl -i -p0e 's/typedef ([^*;{}]+) (\w+);/using \2 = \1;/sg'
Patchset 2 then adds some manual changes for typedefs for pointer types,
where the regular expression did not match.

When ASAN is enabled, the previous implementation of
Isolate::GetIncumbentContext didn't work well due to mixture of fake
and real stack frames.
This patch converts an address in the fake stack frame to an address
in the real stack frame so that we can compare two addresses.

This is done now while embedders have yet to adapt to the new API before
it becomes hard to migrate.
Also renamed variable/methods to use "worker threads" rather than
"background" nomenclature.

With a temporary intermediate step to allow adapting embedders before
getting rid of the ExpectedRuntime method altogether.
The method is being renamed to CallOnWorkerThread() as an effort to
go away from "background" nomenclature for worker threads ("background"
usually refers to a priority but worker threads are commonly used for
high priority tasks in v8).
Other CLs will follow to rename other "background" APIs.
