    build,win: fail fast in vcbuild without cargo

    On Windows, configure.py returns from check_compiler() before it gets
    to the cargo and rustc check, so Temporal stays enabled even when no
    Rust toolchain is installed. The build then runs for a long time and
    fails in node_crates.vcxproj with MSB8066.

    Check for cargo in vcbuild.bat before configuring and building, in the
    same places deps/crates/cargo_build.py looks, and stop with a message
    pointing to BUILDING.md. The check is skipped for nobuild, clean, and
    when Temporal is disabled or provided as a shared library.
