For CONFIG_USERSPACE the input from gen_app_partitions.py there is
a need to be able to specify input files as well as input sections
patterns for zephyr_linker_section_configure(). This is used for
app partitions from libraries (which generate input patterns like
foo.a:*(.data*)).
This adds documentation to zephyr_linker_section_configure() to clarify
what INPUT allows, and also adds some parsing tricks to ld_script.cmake
to properly add the file patterns when they are missing.
