linux-yocto: conditionally add clang/rust/bindgen-cli-native to DEPENDS

Conditionally add 'clang-native', 'rust-native' and 'bindgen-cli-native' to 'DEPENDS'
when Kernel Rust Support is enabled.

These tools are required for building Rust-enabled kernels and for
generating Rust FFI bindings via bindgen during the kernel build.

This ensures the additional dependencies are only pulled in when
Rust support is explicitly enabled, avoiding unnecessary native
dependencies for non-Rust kernel builds.
