[PATCH 2/4] python3-build: upgrade 1.5.1 -> 1.6.0

[Richard Purdie <richard.purdie@linuxfoundation.org>]

Features:
    - Add --report=PATH to write a machine-readable JSON report of built artifacts; --metadata
      now also accepts .whl files - by @gaborbernat (#198)
    - The srcdir argument now accepts .tar.gz source distributions, extracting and building from
      them - by @gaborbernat (#311)
    - The “Unmet dependencies” error from --no-isolation builds now shows the wanted version,
      found version, and interpreter - by @gaborbernat (#504)
    - Add --sdist-extract-dir to extract the intermediate sdist into a persistent directory,
      enabling compiler cache reuse across rebuilds - by @gaborbernat (#614)
    - Add --env-dir to place the isolated build environment at a fixed path, enabling compiler
      cache reuse across builds - by @gaborbernat (#655)
    - Print a summary of resolved dependency versions (name==version) after installing them in
       isolated builds - by @gaborbernat (#959)
    - On build failure, print a tip pointing to --env-dir and --sdist-extract-dir for debugging and
      link to the “Debug a failed build” how-to - reported by @dimpase, implemented by @gaborbernat (#966)

Bugfixes:
    - Drain verbose subprocess output inline instead of using a ThreadPoolExecutor, which silently
      swallowed logging errors - by @henryiii (#1098)
    - Reject a file passed as --env-dir with a clear error instead of a raw FileExistsError - by @henryiii (#1100)
    - Emit CLI warnings to stderr instead of stdout, so they no longer corrupt --metadata
      JSON output on stdout - by @ymyzk (#1111)
    - Fix the Windows symlink support probe always returning False due to a stale object
      interpolated into the destination path - by @henryiii (#1118)
    - Fix metadata_path’s build-backend fallback returning a nonexistent dist-info path for wheels
      with a build tag - by @henryiii (#1119)
    - Write pip/uv requirements and constraints files with \n instead of os.linesep, avoiding doubled
      \r\r\n line endings on Windows - by @henryiii (#1120)
    - Batch of small robustness fixes: correct macOS release parsing for the minimum pip version, avoid
      sharing the mutable default build-system table between builders, keep the original error when
      isolated-environment setup fails early, and raise BuildException for an invalid wheel - by @henryiii (#1121)
    - Decide color support independently for stdout and stderr instead of only checking stdout.isatty(),
      so redirecting one stream no longer disables or leaks ANSI colors on the other - by @henryiii (#1123)
    - Pass --dependency-constraints-txt files through to the installer unmodified instead of re-parsing them
      into a deduplicated set of lines, fixing a case where a hashed requirement (e.g. from pip-compile
      --generate-hashes) could have its --hash continuation line separated from its requirement line and
      silently dropped, depending on the interpreter’s hash seed - by @manfred-kaiser (#1140)

Removals:
    - Remove exc_info parameter and attribute from BuildBackendException. - by @layday (#1161)
