Uses a dynamically allocated buffer to hold the CSV data, which can then be written to an output file.

Changes include:

* nxdt_utils: add utilsEscapeCharacters().

* title: add titleGenerateTitleRecordsCsv().
* title: move core logic from titleGetUserApplicationData() into _titleGetUserApplicationData(). titleGetUserApplicationData() now only takes care of duplicating the retrieved data.
* title: update titleGetContentInfosByGameCardContentMetaContext() to make it write the forged NcmContentInfo entry for the Meta NCA at the end of the returned buffer.
* title: fix a bug in titleRefreshGameCardTitleInfo() that prevented a title info's metadata pointer to be updated after retrieving application metadata via ns.
* title: update titleGenerateGameCardApplicationMetadataArray() to add a logfile warning if an application entry doesn't have a valid application metadata pointer.
* title: make _titleGenerateGameCardFileName() a bit easier to read.
