clamav: Add recipe for version 1.4.3

Add modern ClamAV 1.4.3 recipe with comprehensive improvements over
the legacy 0.104.4 version. Remove the end-of-life 0.104.4 recipe and
associated patches as they are superseded by this version.

Major changes in 1.4.3:
- Upgraded core engine with improved threat detection capabilities
- Added Rust components requiring cross-compilation support
- Updated CMake build system replacing legacy autotools
- Modernized library dependencies (LLVM, JSON-C, PCre2)
- Added comprehensive license compliance for multi-component package
- Enhanced cross-compilation support for all target architectures

The recipe includes dynamic Cargo configuration using Yocto variables
to support cross-compilation to any target architecture supported by
the build system.

Runtime configuration improvements:
- Set APP_CONFIG_DIRECTORY to ${sysconfdir}/clamav for proper config paths
- Added volatiles/tmpfiles support for /var/lib/clamav and /var/log/clamav
- Added pkg_postinst scripts to ensure correct directory ownership
- Implemented CMake cache variables for cross-compilation
- Updated all license checksums for compliance
- Added Rust toolchain integration with automatic environment setup
- Use Cargo vendoring with cargo + cargo-update-recipe-crates classes

Security rationale:
- ClamAV 0.104.4 reached end-of-life and is no longer maintained
- Upstream strongly recommends migration to 1.4.x for security updates
