Starlarkify cc_common.empty_variables (#806)

Replace the Java-backed `cc_common.empty_variables()` call with `_cc_internal.cc_toolchain_variables(vars = {})`. Both implementations construct the same empty `CcToolchainVariables` representation, preserving compile, link, FDO, and toolchain feature expansion.

Validation: `buildifier -mode=check cc/private/cc_common.bzl` and 66 passing C++ common, compile-variable, link-variable, and FDO analysis tests.

Closes #806
