Custom devoptab wrappers (part 1). This commit implements a devoptab wrapper for Partition FS sections within NCAs, using code from pfs.c/h. Other changes include: * codebase: use NX_IGNORE_ARG macro where needed. * hfs: slight tweaks to some of the static functions. * pfs: slight tweaks to some of the static functions. * pfs: use pfsIsValidContext() where needed. * utils: update utilsInitializeResources() to use __system_argc and __system_argv variables from libnx. * todo: update text file.

Improve directory layout while we still can. The directory layout is partially based on the C++ namespaces we're currently using. Other changes include: * devoptab: move directory into "core". * fatfs: move directory into "core". * GameCardTab: move portions of logic from PopulateList() into their own methods. * GameCardTab: use a macro to generate the properties table. * GameCardTab: use a macro to add ListItem elements. * GameCardTab: update AddApplicationMetadataItems() method to also display the number of DLCs available in the inserted gamecard for each application whenever possible. * Makefile: remove all extra entries from the INCLUDES variable. * nxdt_includes: move HOS version structs into their own header file. * tasks: move code for each individual task into its own file(s). * title: update titleGetGameCardApplicationMetadataEntries() to also count the number of DLCs available in the inserted gamecard for any given base application. * title: reorder gamecard application metadata entries by name before returning the buffer in titleGetGameCardApplicationMetadataEntries().
