Don't include windows.h from platform.h

[stweil]

This partially reverts commit c150b98.
Now params.cpp includes host.h which also gets the definition for MAX_PATH.

This addresses issue #2390.

Do you think it there reason to keep host.h and platform.h separated?
host.h is used only in few places:

src/ccmain/paragraphs.cpp:#include "host.h"                 // for NearlyEqual
src/ccmain/recogtraining.cpp:#include "host.h"  // for NearlyEqual
src/ccstruct/blobbox.cpp:#include "host.h"        // for NearlyEqual
src/ccstruct/blobbox.h:#include "host.h"              // for PRId32
src/ccstruct/boxword.cpp:#include "host.h"       // for NearlyEqual
src/ccstruct/imagedata.cpp:#include "host.h"        // for PRId64
src/ccstruct/ocrpara.cpp:#include "host.h"  // For NearlyEqual()
src/ccstruct/pdblock.cpp:#include "host.h"  // for PRId32
src/ccstruct/polyblk.cpp:#include "host.h"  // for PRId32
src/dict/dawg.h:#include "host.h"               // for PRId64

Yes, see my comment.

The more difficult question is whether we may remove host.h from the 4.1 API.

Do not worry about that - I can ran abi-compliance-checker locally so I will backport all possible changes from master.

Also I found nice extension for Visual studio that eliminate not needed includes (which is based on include-what-you-use), so maybe we can better optimize includes.
