ld: Move note sections after .rodata section

Move note sections after .rodata section so that note sections are
placed in the same PT_LOAD segment together with .rodata section,
instead of a separate PT_LOAD segment.

	PR ld/32341
	* scripttempl/misc-sections.sc: Move note sections to ...
	* scripttempl/elf.sc: Here, after .rodata section.
	* testsuite/ld-elf/pr32341.d: New file.
	* testsuite/ld-elf/pr32341.s: Likewise.
