fix: enable C++ toolchain auto-configuration for Rust binaries

Fixed the cc_configure extension name and added .bazelrc to enable
--incompatible_enable_cc_toolchain_resolution. This matches the
rules_wasm_component configuration and enables proper C++ toolchain
detection for rust_binary targets like wasm_embed_aot.

Changes:
- Fixed cc_configure extension name in MODULE.bazel
- Added .bazelrc with C++ toolchain resolution enabled
- Simplified release workflow AOT build command
