Extract Windows logic for c++ autoconfiguration into a separate Starlark rule This cl redirects windows_cc_configure to use a templated BUILD file and its own cc_toolchain_config implementation. It also extracts the logic that creates CcToolchainConfig info for armeabi-v7a into a separate rule. RELNOTES: None. PiperOrigin-RevId: 249011904
