  devel/llvm22: add LLVM 22 (#733)

Import LLVM 22.1.8 and adapt the compiler runtimes, target handling, and
patches for MidnightBSD.

AI-Assisted-by: OpenAI Codex <noreply at openai.com>

## Summary by Sourcery

Add a new llvm22 port providing LLVM 22.1.8 and Clang toolchain for
MidnightBSD, and register it in the ports framework.

New Features:
- Introduce devel/llvm22 port packaging LLVM 22.1.8 with Clang, LLD,
LLDB, MLIR, OpenMP, Flang, and related tools and runtimes, with default
and lite flavors.
- Support MidnightBSD-specific triples, ELF OSABI handling, system
detection, and preprocessor macros across LLVM, Clang, compiler-rt, and
LLDB so the toolchain recognizes MidnightBSD as a FreeBSD-family OS.

Bug Fixes:
- Work around platform-specific issues in compiler-rt floating-point
helpers, ELF profiling, and Flang environment handling on MidnightBSD
and i386.
- Ensure clang-format helper scripts use the version-suffixed
clang-format binary installed by the llvm22 port, avoiding path and
version conflicts.

Enhancements:
- Extend the shared llvm.mk infrastructure to accept LLVM version 22,
enabling consumers to depend on this new toolchain version.
- Adjust build configuration, rpath handling, and Sphinx doc generation
to work correctly on MidnightBSD and integrate with the existing ports
options model for backends and components.
- Refine compiler-rt runtime configuration and sanitizer support
matrices to treat MidnightBSD similarly to FreeBSD, including profile
and sanitizer libraries across supported architectures.

Documentation:
- Hook LLVM and subproject manpage and documentation installation into
MidnightBSD’s ports layout with versioned suffixes for the llvm22
toolchain.

Tests:
- Retain the llvm do-test target wiring for the new port so upstream
lit-based tests can be run when enabled.
