Improvements in --debug-print switch implementation.

* Renamed print_settings_initializer.* into print_settings_conversion.*
* Dump on FILE thread.
* Added PrintSettingsToJobSettingsDebug to dump PrintSettings.
* Added PrintedDocument::CreateDebugDumpPath for consistent dump file naming.
* Dump PDFs received from renderer process.
* Moved GetCustomMarginsFromJobSettings into print_settings_conversion.cc.
* Moved Parsing PageRanges into print_settings_conversion.*
