Merge #14585: refactor: remove usage of locale dependent std::isspace

15db77f4dd Don't rely on locale dependent functions in base_blob<BITS>::SetHex(...) (uint256), DecodeBase58(...), ParseMoney(...) and ParseHex(...) (practicalswift)

Pull request description:

  Don't rely on locale dependent function `std::isspace` in `base_blob<BITS>::SetHex(...)` (uint256), `DecodeBase58(...)`, `ParseMoney(...)` and `ParseHex(...)`.

  Rationale:

  ```
  $ uname -s
  Darwin
  $ cat poc.cpp
  #include <iostream>
  #include <locale>

  int main(void) {
      setlocale(LC_ALL, "");
      std::cout << std::isspace(133) << ' ' << std::isspace(154) << ' ' << std::isspace(160);
      std::cout << '\n';
  }
  $ clang++ -o poc poc.cpp
  $ ./poc
  1 0 1
  $ LC_ALL=en_US ./poc
  1 0 1
  $ LC_ALL=C ./poc
  0 0 0
  $ LC_ALL=ru_RU.KOI8-R ./poc # an "interesting" locale
  0 1 0
  ```
