Mike Kaganski a5a49657dc tdf#158442: fix opening hybrid PDFs on Windows 
Commit 046e954595 (Try to revert to use
of file_iterator from boost on Windows, 2023-10-31) had introduced a
problem that pdfparse::PDFReader::read couldn't create file_iterator
for files already opened with write access: mmap_file_iterator ctor
on Windows used single FILE_SHARE_READ as dwSharedMode parameter for
CreateFileA WinAPI; and that failed, when the file was already opened
using GENERIC_WRITE in dwDesiredAccess - which happens when opening
stream in TypeDetection::impl_detectTypeFlatAndDeep.

Fix this by patching boosts' mmap_file_iterator constructor to use
FILE_SHARE_READ | FILE_SHARE_WRITE, like we do in osl_openFile.

But there was a pre-existing problem of using char-based CreateFileA
API, which disallows opening any files with names not representable
in current Windows codepage. Such hybrid PDF files would still fail
creation of the file_iterator, and open as PDF.

Fix that by further patching boost to have wstring-based constructors
for file_iterator and mmap_file_iterator on Windows, which would call
CreateFileW.

uses the smart pointers, pool memory and binders functionality.
