Implement the //NON_IDENTICAL_DISCARD suffix from POSIX:2024.

ICONV_SET_DISCARD_INVALID, ICONV_GET_DISCARD_NON_IDENTICAL,
ICONV_SET_DISCARD_NON_IDENTICAL): New macros.
* lib/converters.h (struct conv_struct): Change type of discard_ilseq to
'unsigned int'.
(DISCARD_INVALID, DISCARD_UNCONVERTIBLE): New macros.
* lib/iconv.c (iconv_open, iconv_open_into): Change type of
discard_ilseq to 'unsigned int'.
(iconvctl): Implement ICONV_GET_DISCARD_INVALID,
ICONV_SET_DISCARD_INVALID, ICONV_GET_DISCARD_NON_IDENTICAL,
ICONV_SET_DISCARD_NON_IDENTICAL. Change the implementation of
ICONV_GET_DISCARD_ILSEQ, ICONV_SET_DISCARD_ILSEQ to test/set both bits.
* lib/iconv_open1.h: Update comment. Recognize //NON_IDENTICAL_DISCARD.
* lib/iconv_open2.h: Update comment.
* lib/loop_unicode.h (mb_to_uc_write_replacement): Test the
DISCARD_UNCONVERTIBLE bit of discard_ilseq.
(unicode_loop_convert): Test the respective bit of discard_ilseq.
(unicode_loop_reset): Test the DISCARD_UNCONVERTIBLE bit of
discard_ilseq.
* lib/loop_wchar.h (wchar_from_loop_convert, wchar_to_loop_convert):
Test the DISCARD_INVALID bit of discard_ilseq.
* man/iconv_open.3: Mention the //NON_IDENTICAL_DISCARD suffix. Mark as
conforming to POSIX:2024.
* man/iconv.3: Likewise.
* man/iconv_close.3: Mark as conforming to POSIX:2024.
* man/iconv.1: Likewise.
* man/iconvctl.3: Document ICONV_GET_DISCARD_INVALID,
ICONV_SET_DISCARD_INVALID, ICONV_GET_DISCARD_NON_IDENTICAL,
ICONV_SET_DISCARD_NON_IDENTICAL. Revise the description of
ICONV_GET_DISCARD_ILSEQ, ICONV_SET_DISCARD_ILSEQ.
* tests/test-discard.c (test_default, test_translit, test_ignore,
test_ignore_translit): Test also the ICONV_GET_DISCARD_INVALID,
ICONV_GET_DISCARD_NON_IDENTICAL accessors.
(test_nid, test_nid_translit, test_invd, test_invd_translit): New
functions.
(main): Add test cases with //NON_IDENTICAL_DISCARD suffix.
