gallium/hud: dump hud_driver_query values to files

Dump values for every selected data source in GALLIUM_HUD.

Every data source has its own file and the filename is
equal to the data source identifier.

Set GALLIUM_HUD_DUMP_DIR to dump values to files in this directory.

No values are dumped if the environment variable is not set, the
directory doesn't exist or the user doesn't have write access.
