Remove generic C overrides for chroma and luma intra prediction in ihevcd_init_function_ptr_rext_generic to allow architecture-specific assembly and SIMD intrinsics to be used during 422 and 444 decoding.

libhevcdec: Enable architecture-specific SIMD optimizations for 422 and 444
...
Previously, when 422 or 444 chroma formats were encountered, all
function pointers were overridden to generic C implementations due to
lack of support in optimized assemblies/intrinsics for certain
components.
This change introduces `ihevcd_init_function_ptr_rext` which:
- First initializes all function pointers with architecture-optimized
versions.
- Explicitly overrides only the components not yet optimized for 422/444 formats (intra prediction, SAO, deblocking and chroma padding) to point
back to their C implementations.
This allows other fully-compatible modules (e.g: inter prediction modes, transform/reconstruction, format conversion) to benefit from SIMD
optimizations on 422/444 formats without degrading YUV 420 decoding.
Test: ./hevcdec

ihevcd_itrans_res_dc is defined in common folder but has a wrong prefix of ihevcd_.
This is now fixed to ihevc_.

Bypass wrappers functions for memcpy and memset, calling standard
C library functions directly. This allows _FORTIFY_SOURCE to
perform compile-time safety checks.
