Subject: [PATCH] build: Fix build errors on Windows

- Fix string no output variables on UWP

  On UWP, CMAKE_SYSTEM_PROCESSOR may be empty. As a result:
  string(TOLOWER ${CMAKE_SYSTEM_PROCESSOR} TARGET_ARCHITECTURE)
  will be treated as:
  string(TOLOWER TARGET_ARCHITECTURE)
  which, as a result, will cause a CMake error:

  CMake Error at CMakeLists.txt:42 (string):
    string no output variable specified

- Remove unnecessary header inclusions in uchardet.cpp

  These extra inclusions cause build errors on Windows.
