refactor(dev-lang/dart): mainline readability and layout cleanup

Refactor the Dart packaging and generator tooling for mainline readability
and Gentoo conventions, superseding the partial work from PR #924:

- Replace the flat positional 4-tuple DART_DEPENDENCY_ARCHIVES array with
readable record-oriented DART_DEPENDENCY_TREES mapping unpacked archive
trees directly to their source destinations.
- Replace custom tar -xf unpacking in src_unpack() with standard Portage
default unpack followed by atomic tree moves into $.
- Rename maintainer generator tooling from scripts/generate-ebuild.py to
scripts/generate_dart_ebuild.py with matching unit tests.
- Adopt stable semantic block delimiters: BEGIN/END GENERATED DART DEPS.
- Simplify generated SRC_URI metadata by removing unnecessary org-variable
indirection while keeping revision pinning explicit.
- Update declared LICENSE across Dart ebuilds to accurately reflect bundled
components (Apache-2.0, Apache-2.0-with-LLVM-exceptions BSD MIT
Unicode-3.0 ZLIB).
- Ensure dart-bin declares BDEPEND="app-arch/unzip" instead of RDEPEND.
- Update cache metadata in metadata/md5-dict for modified packages.
- Add unit tests verifying the readable generated representation, devtools
mapping, byte-stable regeneration, and default unpack phase.

dev-lang/dart: use stable content-addressed sources

Gitiles regenerates archive bytes for every request, which makes Manifest verification impossible. Resolve DEPS commits through exact GitHub mirrors, omit audited build-irrelevant entries, and fix the current pkgcheck findings.

dev-lang/dart: make source build inputs reproducible

Replace the incomplete source graph with a DEPS-derived set of pinned archives, declare the unavoidable self-hosting seed as a private build-only package, and build the SDK through upstream GN/Ninja with the system toolchain. Also make PR manifest verification inspect the checked-out revision.
