Merge #20429: refactor: replace (sizeof(a)/sizeof(a[0])) with C++17 std::size
e829c9afbf75e930db6c3fe77a269b0af5e7a3ad refactor: replace sizeof(a)/sizeof(a[0]) by std::size (C++17) (Sebastian Falbesoner)

63d4ee1968144cc3d115f92baef95785abf813ac refactor: iterate arrays via C++11 range-based for loops if idx is not needed (Sebastian Falbesoner)
Pull request description:
This refactoring PR picks up the idea of #19626 and replaces all occurences of `sizeof(x)/sizeof(x[0])` (or `sizeof(x)/sizeof(*x)`, respectively) with the now-available C++17 [`std::size`](https://en.cppreference.com/w/cpp/iterator/size) (as [suggested by sipa](https://github.com/bitcoin/bitcoin/pull/19626#issuecomment-666487228)), making the macro `ARRAYLEN` obsolete.
As preparation for this, two other changes are done to eliminate `sizeof(x)/sizeof(x[0])` usage:
* all places where arrays are iterated via an index are changed to use C++11 range-based for loops If the index' only purpose is to access the array element (as [suggested by MarcoFalke](https://github.com/bitcoin/bitcoin/pull/19626#discussion_r463404541)).
* `std::vector` initializations are done via `std::begin` and `std::end` rather than using pointer arithmetic to calculate the end (also [suggested by MarcoFalke](https://github.com/bitcoin/bitcoin/pull/20429#discussion_r567418821)).
