tdf#114635: reimplement TWAIN-based scan using 32-bit shim on Windows

Since TWAIN is only actually available as 32-bit component on Windows,
to use it in a 64-bit program, we need a 32-bit shim program that does
all actual communication with TWAIN subsystem.

This change reimplements TWAIN implementation to be a separate 32-bit
process. Image is transfered from the shim to main program using file
mapping API.

This reverts most of commit 585d9806961342e95f7318fb947bd31e9f86dee0.
64-bit LibreOffice doesn't bundle TWAIN DSM library now. TWAIN DSM
source code is still used for TWAIN headers.
