Resolves#97.
We used to detect target platform by inspection of VCPKG_TARGET_TRIPLET, but that is no longer necessary. As a result, this enforcement can be removed.
* Remove the need to specify the target architecture by testing CMAKE_CXX_COMPILER_ARCHITECTURE_ID.
This is somewhat fragile because it's documented as an internal-to-cmake variable, but FindBoost.cmake has used it 'effectively forever' so I'm not too concerned.
* Make ARM and ARM64 work, and use CMAKE_CXX_STANDARD_LIBRARIES for kernel32.lib.
* Affirmatively set _HAS_OLD_IOSTREAMS_MEMBERS=1 to make intellisense in "Open Folder" happy.
* Use add_library(STATIC) and STATIC_LIBRARY_OPTIONS for implib smashing instead of add_custom_command et al.
* Include headers in some of the generated targets so they show up in "open folder" et al.
* Extract the target architecture from VCPKG_TARGET_TRIPLET.
* Add .vs and out/ to .gitignore as VS's open folder creates these.
* Don't link an exe in try_compile.
* Add CMakeSettings.json to make VS happy.
