Add pdf targets to CMake build system

This comes with a few additional changes - Japanese font selection logic is reduced to a minimum. That is, one can pass fonts and a font directory on the cmake command line with the appropriate -D flags, but none of these are checked for correctness. I thought of porting the autotools rules for this but looking closer they are totally broken. If really needed an improved variation could be written later in cmake. - Every fop run now requires a fop config file (fop.xconf) in cmake. This allows fop to find our figures in the source tree instead eliminates the need for a link or copy of these figures in the build tree. The existing config files for Russian and Japanese are amended for this. - All settings that just mimic the defaults have been removed from the Japanese fop config file. In addition the target structure has been slightly re-arranged. There are a few global targets like html, check, pdf, xml. Each of these will depend on the equivalent targets per document. For example: the global html target depends on gnucash-guide-html and gnucash-help-html. Each of these in turn then depend on the equivalent targets per language. For example gnucash-help-html in turn depends on C-gnucash-help-html, it-gnucash-help-html and so on. This allows to make all documents in one go or only one document in all supported languages or only one single document.
