Add action_config and feature for linking on Windows

Also implemented whole archive feature on Windows

1. Pulled action_configs and features from CppLinkActionConfigs.java

2. Deleted many features not working on Windows. (AFAIK)
   including:
       symbol_counts
       output_execpath_flags_executable
       global_whole_archive_open
       runtime_root_flags
       global_whole_archive_close
       force_pic_flags

3. Added c++-link-interface-dynamic-library action config
   Not sure there is such thing on Windows, but it's currently in MANDATORY_LINK_TARGET_TYPES

4. Added build variable "whole_archive_object_files_params"

5. Automatically detect if linker supports /WHOLEARCHIVE and use the corresponding build variable
