Cleanup RenderThemeWin.

Try to bring a bit more structure to RenderThemeWin.  This will help as Mac and Linux try to match it.

  - Remove trailing whitespace and extra newlines.
  - Reorder some declarations in the header to
    better group similar methods.
  - Drop unimplemented declaration of addIntrinsicMargins.
  - Implement the empty RenderThemeWin constructor and
    destructor in the header file.
  - Reorder all implementations to match declaration order.
  - Move the enums into the anonymous namespace.
  - Don't indent in an anonymous namespace.
  - Move all internal static helpers together.

This patch is gnarly, sorry.  It compiles, that's about the most I can say.

This will really help in getting RenderThemeGtk to match.  The render theme
stuff is a ton of virtual overrides, and right now it's really hard to tell
whose implement what, or what we're missing, etc.  This helps a lot.

No code change (hopefully).
