ci/doc:install libunwind-19 & libc++-19

[luoliwoshang]

with clang++ #1147

test with Homebrew/homebrew-core#227010

• use llvm/libunwind to instead libunwind because the llvm/libc++ is conflict with independant libunwind
• add "-L#{llvm.opt_lib} to support link -lc++

This change need test homebrew compatible:

1. Create a release on your cloned repo (stable version).
2. Create a PR to test this release on homebrew-core's LLGo formula.

got it ,i will test it ,is it for homebrew-linux?

Creating a PR on homebrew-core triggers tests on both macOS and Linux. Testing only on your local machine is insufficient, as some cases might be broken on Homebrew's pre-built bottles, only a homebrew-core PR can cover these pre-built tests.

• create a test release for current update for libwind-19-dev & libc++-19-dev https://github.com/luoliwoshang/llgo/releases/tag/v0.1.0
• corespoding pr in homebrew [wip] llgo:prerelease-testing with libwind-19-dev & libc++-19-dev Homebrew/homebrew-core#227010

Additionally, for Homebrew's llvm@19 on Linux, it seems to automatically include libunwind and libc++, so they don't need to be installed separately like with apt. That is why I did not add them as extra installations in the formula.

Need fix tap syntax to pass the [CI / conclusion (pull_request)] step to test pre-built bottles, some errors happened before.

tap syntax now is passed

Homebrew/homebrew-core#227010 the ci test is passed,and i add the cpp/std.str 's test to ensure this case #1146 is fixed correctly in homebrew's llgo

    assert_equal "Hello LLGO by fmt.Println\n" \
                 "Hello LLGO by c.Printf\n" \
                 "Hello LLGO by cpp/std.Str\n",
                 shell_output("#{bin}/llgo run .")
    # Test llgo build
    system bin/"llgo", "build", "-o", "hello", "."
    assert_equal "Hello LLGO by fmt.Println\n" \
                 "Hello LLGO by c.Printf\n" \
                 "Hello LLGO by cpp/std.Str\n",
                 shell_output("./hello")

with the clang++ update , we need use the libc++ , at apt-get need install libc++-19-dev but in the brew,libc++ is with llvm,so we not need addtional depend libc++.

and with the independent libunwind is conflict with libc++,so i change it to use llvm's libunwind
