As a WT developer, I want to be able to compile the wiredtiger library target (libwiredtiger[.a,.so]), the Python API and C/C++ tests for Windows, using CMake.

Definition of done:

• Can invoke CMake in the wiredtiger repository. This should be able to successfully configure/generate a Ninja build on:
  • Windows platforms.
  • For supported compilers: GCC & Clang.
• Supports static and shared library builds
• Supports the different extension configurations (e.g  compressors)
• Working ninja build that successfully creates a libwiredtiger[.a,.so] file
• Support compiling Python API
• Support compiling C/C++ tests
• Updated documentation for new architectures (if needed) on how to build library with CMake (e.g. README) 
• SCons build still works as expected (should co-exist in tree)
