DTC 1.8.0

Changes since v1.7.2 include:
 * dtc
   - Add informative error for stray identifiers (e.g. unexpanded macros)
   - Better decompiling of plugins
     - Restore labels from __symbols__ node when possible
     - Restore phandle references from __local_fixups__ and __fixups__
       when possible
     - Improve type guessing when compiling to dts format
   - Add only new data to fixup nodes instead of complete regeneration

 * libfdt
   - Add fdt_setprop_namelen() and fdt_setprop_namelen_string()
   - Add fdt_get_property_namelen_w()
   - Add fdt_find_string_len_()
   - Introduce fdt_downgrade_version()
   - Verify alignment of sub-blocks in dtb
   - Handle FDT_NOP tags before FDT_END in fdt_check_full()
   - Document most remaining functions in libfdt.h
   - Standardise "returns:" annotation in documentation

 * checks
   - Warn about missing #address-cells for interrupt parents
   - Relax avoid_unnecessary_addr_size to allow child ranges properties
   - Fix detection of 'i2c-bus' child node
   - Remove check for graph child addresses (redundant with schema validation)
   - Do not check overlays for alias paths

 * fdtdump
   - Remove overly strict dtb version check

 * pylibfdt
   - Fix backwards compatibility of return values with SWIG v4.3
   - Port python bindings to build natively via meson and meson-python

 * Build
   - Deprecate Makefile in favor of Meson
   - Support building libfdt without static library
   - Don't build test programs by default
   - Fix -Dtools=false build
   - Add FreeBSD and non-GNU linker compatibility

 * CI
   - Add macOS build to GitHub Actions
   - Add Cirrus CI for FreeBSD testing
   - Add GitLab CI for Linux builds
   - Update GitHub Actions ubuntu runner to 24.04
   - Skip swig install for mingw32 Windows build

 * Tests
   - Add compatibility with uutils (Rust coreutils)
   - Mark .so from asm output as non-executable stack (glibc-2.41 compat)

 * General
   - Consider drive letters when checking absolute paths on Windows
   - Add AI contribution guidelines
   - Assorted bugfixes and cleanups
   - Add clang-format config
   - Add SBOM file in CycloneDX format
