Subject: feat(ascendc): add Huawei Ascend C toolchain support

Add toolchain, language, rules, and compiler modules for the
bisheng compiler driver from CANN (Compute Architecture for
Neural Networks) toolkit. Supports .asc (Ascend C kernel) and
.aicpu (AI-CPU operator) source kinds with binary/static/shared
target types.

- Toolchain: SDK auto-detection via ASCEND_HOME_PATH env or --sdk
- Compiler: bisheng module inherits from clang, adds add_sourceflags
  for explicit sourcekind overrides
- Rules: ascendc.env (default C++17), npuarchs (--npu-arch), build
- Language: check_main detection, add_ascnpuarchs API
- Tests: unit tests for check_main, project tests for libs/mixed

Fixes #7506
