contrib: replace deprecated --deep codesign flag, fix accidental --verify skip on ci #34914

   Replace the deprecated codesign --deep with explicit, and minimal, per-component signing of Frameworks, Plugins and the top-level bundle.

   The CI signature check introduced in #34787 is updated to use --strict.

   Can be tested with:

   cmake -B build -DBUILD_GUI=ON
   # delete artifacts before rebuilding the `deploy` target
   rm -rf build/Bitcoin-Qt.app build/bitcoin-macos-app.zip
   cmake --build build -t deploy
   codesign --verify --deep --strict --verbose=4 build/dist/Bitcoin-Qt.app
   

   Fixes #32486, supersedes #33592 (this is a condensed version)

   Additionally this PR modifies 03_test_script.sh to avoid modifying GOAL in place. That was causing the codesign --verify step to get skipped entirely.

   Concept ACK. This is a smaller diff than in #33592 :)

   codesign --verify --deep --strict --verbose=4

   You can also update the CI check to also use --strict: https://github.com/bitcoin/bitcoin/blob/2fe76ed8324af44c985b96455a05c3e8bec0a03e/ci/test/03_test_script.sh#L160

   Done

10. ci: avoid modifying GOAL in 03_test_script.sh

    The modification caused "codesign --verify" to be silently skipped.
    
    Introduce BUILD_TARGETS for the cmake target list so GOAL remains
    unmodified throughout the script.

11. contrib: remove deprecated --deep codesign flag

    Replace the deprecated `codesign --deep` with explicit per-component
    signing of Frameworks, Plugins and the top-level bundle.
    
    CI is updated to verify with --strict.
    
    Can be verified with:
    codesign --verify --deep --strict --verbose=4 build/dist/Bitcoin-Qt.app

    I noticed that codesign --verify --strict didn't appear in the log. Looks like we forgot to check that in #34787 review. The problem is that 03_test_script.sh modifies GOAL. Added a commit to reduce the chances of that happening again.

    The GOAL mutation was introduced here: https://github.com/bitcoin/bitcoin/pull/33810/changes/2c78814e0e182853ce44d9fd63d24ee6cab5223e

    It was trying to avoid passing all to cmake --build when GOAL=codegen, which this PR addresses by introducing BUILD_TARGETS instead.

    Tested ACK 5a102a5fc2d1346f6a3aef2008610aea80aaefa7

    Tested on macOS 26 (Darwin 25.5.0), arm64, Apple clang 21, Qt 6 from Homebrew.

    Built the deploy target on this branch and on master (2063f02bd5). The PR contains no src/ changes, so this isolates the signing method:

    • This branch (per-component signing): codesign --verify --deep --strict --verbose=4 build/dist/Bitcoin-Qt.app → valid on disk / satisfies its Designated Requirement. All 32 nested components under Contents/Frameworks/ and Contents/PlugIns/ also pass individual codesign --verify --strict, and the signed binary runs.
    • master (--deep signing): the same checks also pass today — so no regression from switching; the gain is no longer relying on a flag deprecated since macOS 13, and signing inside-out (components first, bundle last) per Apple's guidance.

    For d79ef13c27, code review only (I did not run the CI scripts): the previous GOAL mutation meant the "install deploy" comparison could never match, silently skipping the codesign check — BUILD_TARGETS restores it correctly.
