xz: updated to 5.6.4

5.6.4 (2025-01-23)

* liblzma: Fix LZMA/LZMA2 encoder on big endian ARM64.

* xz:

    - Fix --filters= and --filters1= ... --filters9= options
      parsing. They require an argument, thus "xz --filters lzma2"
      should work in addition to "xz --filters=lzma2".

    - On the man page, note in the --compress and --decompress
      options that the default behavior is to delete the input
      file unless writing to standard output. It was already
      documented in the DESCRIPTION section but new users in
      a hurry might miss it.

* Windows (native builds, not Cygwin): Fix regressions introduced
  in XZ Utils 5.6.3 which caused non-ASCII characters to display
  incorrectly. Only builds with translation support were affected
  (--enable-nls or ENABLE_NLS=ON). The following changes affect
  builds that have translations enabled:

    - Require UCRT because MSVCRT doesn't support UTF-8
      locales and thus translations won't be readable on
      Windows 10 version 1903 and later. (MSVCRT builds
      are still possible with --disable-nls or ENABLE_NLS=OFF.)

    - Require gettext-runtime >= 0.23.1 because older versions
      don't autodetect the use of the UTF-8 code page. This
      resulted in garbled non-ASCII characters even with UCRT.

    - Partially fix alignment issues in xz --verbose --list
      with translated messages. Chinese (simplified),
      Chinese (traditional), and Korean column headings
      are misaligned still because Windows and MinGW-w64
      don't provide wcwidth() and XZ Utils doesn't include
      a replacement function either.

* CMake: Explicitly disable unity builds. This prevents build
  failures when another project uses XZ Utils via CMake's
  FetchContent module, and that project enables unity builds.

* Update Chinese (traditional) and Serbian translations.
