[bazel] Load cc_library from @rules_cc in vulkan_sdk.bzl (#241739)
Explicitly load `cc_library` from `@rules_cc//cc:cc_library.bzl` in the
`BUILD` files synthesized by `vulkan_sdk_setup` so the repository builds
cleanly when native C++ rules are not autoloaded (Bazel 8/9
`--incompatible_autoload_externally=`).
