avcodec/riscv/hevcdsp: add RVV implementation of deblocking
Implement HEVC deblocking filter using RISC-V Vector extension. The RVV implementation of hevc_v_loop_filter_chroma_8 shows no performance gain over the scalar C version, so disable it for now.
All checkasm tests passed. Benchmarks were performed on Sophon SG2044 with native
FFmpeg timers:
hevc_h_loop_filter_chroma8_c: 47.2 ( 1.00x)
hevc_h_loop_filter_chroma8_rvv_i32: 24.2 ( 1.95x)
hevc_h_loop_filter_luma8_skip_c: 37.7 ( 1.00x)
hevc_h_loop_filter_luma8_skip_rvv_i32: 26.9 ( 1.40x)
hevc_h_loop_filter_luma8_strong_c: 191.3 ( 1.00x)
hevc_h_loop_filter_luma8_strong_rvv_i32: 93.5 ( 2.05x)
