ykiko 592b37417e feat: cross-compile & upgrade LLVM to 21.1.8 (#390)
## Summary

This PR adds cross-compilation support for three new target platforms,
upgrades LLVM to 21.1.8, and overhauls the CI pipelines around
cross-builds and testing.

## Cross-compilation

New target triples accepted via `-DCLICE_TARGET_TRIPLE=...`:

| Target triple | Host | Output |
|---|---|---|
| `x86_64-apple-darwin` | macos-15 (arm64) | macOS x64 |
| `aarch64-linux-gnu` | ubuntu-24.04 (x64) | Linux arm64 |
| `aarch64-pc-windows-msvc` | windows-2025 (x64) | Windows arm64 |

- `cmake/toolchain.cmake` — maps `CLICE_TARGET_TRIPLE` to
`CMAKE_SYSTEM_NAME`/`CMAKE_SYSTEM_PROCESSOR`/compiler `--target`; picks
up conda aarch64 sysroot when cross-compiling Linux.
- `cmake/llvm.cmake` — forwards target platform/arch to `setup-llvm.py`
so the right prebuilt LLVM is downloaded for the target.
- `CMakeLists.txt` — uses a host-side `flatc` from `PATH` under
`CMAKE_CROSSCOMPILING` instead of the in-tree target build.
- `pixi.toml`:
  - Adds `osx-64`, `linux-aarch64`, `win-arm64` platforms.
- New environments: `cross-macos-x64`, `cross-linux-aarch64` (adds
`gcc_linux-aarch64` + `sysroot_linux-aarch64`), `cross-windows-arm64`.
- New lightweight `test-run` env used on native ARM/x64 runners to
execute cross-built artifacts (pulls in upstream clang+lld on macOS so
tests don't fall back to Apple clang).
- `scripts/activate_cross_linux.sh` — exports `CONDA_PREFIX`-relative
paths for the aarch64 toolchain.
- `scripts/build-llvm.py` — `--target-triple` support and a
`build_native_tools()` helper that produces host `llvm-tblgen` /
`clang-tblgen` needed when cross-compiling LLVM itself.

## LLVM upgrade 21.1.4 → 21.1.8

- `cmake/package.cmake` bumps `setup_llvm("21.1.8")`.
- `config/llvm-manifest.json` regenerated with 6 new cross-compiled
entries and a new `arch` field on every entry so lookup is `(version,
platform, arch, lto, build_type)`.
- `scripts/setup-llvm.py` — honours the new `arch` field when resolving
artifacts.
- `scripts/update-llvm-version.py` (new) — single-call version bump
across `package.cmake` + manifest.
- `scripts/validate-llvm-components.py` (new) — scans the LLVM source
tree for library targets and diffs them against
`scripts/llvm-components.json` to catch stale/misspelled component names
before a build.
- `scripts/llvm-components.json` (new) — explicit allow-list of required
LLVM/Clang library targets used by `build-llvm.py`.

## CI changes

- `.github/workflows/build-llvm.yml`:
- Adds `workflow_dispatch` with `llvm_version`, `skip_upload`, `skip_pr`
inputs.
- Matrix extended with the 6 cross-compile entries (2 per new platform:
RelWithDebInfo ± LTO).
- `build clice` / test / prune steps gated on `!matrix.target_triple`
for cross-builds; cross-built LTO entries apply the native prune
manifest (arch-independent).
  - Cross-compiled binary architecture is verified with `file(1)`.
- New `upload` job triggered by `workflow_dispatch` pushes artifacts to
`clice-io/clice-llvm` and hands the manifest off to the next job.
- `.github/workflows/test-cmake.yml`:
- Build matrix gains three `build_only: true` cross entries that upload
`bin/` + `lib/` artifacts.
- New `test-cross` job runs on native `macos-15-intel`,
`ubuntu-24.04-arm`, `windows-11-arm` runners, downloads the cross-built
artifacts, and runs unit / integration / smoke tests under the
`test-run` pixi env.
- Cache keys now include `target_triple` so native and cross builds
don't collide.
- `.github/workflows/publish-clice.yml`:
- Three additional release artifacts for the new targets
(`clice-x86_64-macos-darwin`, `clice-aarch64-linux-gnu`,
`clice-aarch64-windows-msvc`), each with a matching `-symbol` archive.

## Compatibility

- All existing native builds and tests are preserved; cross entries are
additive.
- `Debug` + ASAN remains disabled on Windows (`llvm_mode == Debug && os
== windows-*` no longer appends `-asan`).
