cmake: fix dependencies for copy_data_files

Ensure that files from INSTALL_FILES depend on html_docs, not the parent
target copy_data_files (that would not help at all). Ensure that lua
scripts are generated before copying them (another moved dependency).
Explicitly track the help files that have to be textified for Windows
(this finalizes the addition of proper dependencies to copy_data_files
targets).

Since there is no compelling reason for the extra
copy_data_files_depends target now, remove it and move copy_data_files a
bit further in the file such that the dependencies can be set.

While at it, remove the unnecessary make_directory, the copy_data_files
target will create it automatically when copying a file into it.
