Support alternative but still default application prorile locations

cat /usr/local/bin/nvidia-bug-report.sh | grep application
        append_file_or_dir_silent "$DIR/.nv/nvidia-application-profiles-rc"
        append_file_or_dir_silent "$DIR/.nv/nvidia-application-profiles-rc.backup"
        append_file_or_dir_silent "$DIR/.nv/nvidia-application-profiles-rc.d"
        append_file_or_dir_silent "$DIR/.nv/nvidia-application-profiles-rc.d.backup"
        append_silent "$DIR/.nv/nvidia-application-profile-globals-rc"
        append_silent "$DIR/.nv/nvidia-application-profile-globals-rc.backup"
append_file_or_dir_silent "/etc/nvidia/nvidia-application-profiles-rc"
append_file_or_dir_silent "/etc/nvidia/nvidia-application-profiles-rc.d"
append_file_or_dir_silent /usr/share/nvidia/nvidia-application-profiles-*-rc

The reason nvidia-bug-report.sh appends so many files to the report log is these are all default locations for the rc (and key...) files to exist. For example Clear Linux has a philosophy of viewing /usr/share as sacred and stores its default config files there. /etc/ is a better place for the rc files, imo and allows CL users for example to remove /etc and /var iirc to do a factory reset.

The driver uses the same logic as the bug reporting tool. For nvidia-settings to be anything but impotent it must implement the SAME hunting logic as the driver. Just looking in /usr/share became no longer acceptable after the driver started hunting.

The driver doesn't hunt for 1 file to use it parses each file per application, later entries, later files override previous settings.

See https://download.nvidia.com/XFree86/Linux-x86_64/390.77/README/profiles.html to understand how the logic works.

Start by reviewing the locations collected in /usr/local/bin/nvidia-bug-report.sh and the profiles.html documentation for the driver's profile lookup and override order. Trace the corresponding nvidia-settings profile-loading entry point, then verify that files in all documented default locations are parsed in order and later entries override earlier settings.
