Instead of using runtime calls to generate the Array Literal passed to %reflect_call / %reflect_construct, we create an ArrayLiteral from the list of arguments, and perform spreads using the interpreter mechanism for spreading in ArrayLiterals (thus, the spreading becomes inline). This array literal is still passed to %reflect_call / %reflect_construct as before. This cuts the runtime for bench-spread-call.js -> testSpread roughly in half, and will likely improve further once https://chromium-review.googlesource.com/c/v8/v8/+/915364 has landed.

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.

MSVC 2015 and 2017 implement std::is_trivially_copyable, but not correctly. Hence, reimplement it using more low-level primitives. For stdlibc++ versions below 5.0, we already have a workaround for the missing support of std::is_trivially_copyable, but this is an unsound approximation, because it is ignoring move constructor, move assignment and copy assignment. Therefore, do not use this approximation for asserting trivial copyability of a type. Finally, add unittests for the new is_trivially_copyable implementations.

External references are process-specific and thus need to be accessed through an indirection (or reloc'd by the linker). This CL moves all used external references to the builtins constants table and rewrites accesses to load from there. In the future, this could be made more efficient by removing levels of indirection or using the native linker.

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).
