888d708dcd Fix GEBP half/quarter-packet loops for nr>=8 RHS packing on ARM64 
On ARM64 (and LoongArch64), the GEBP kernel uses nr=8, so the RHS is
packed in 8-column blocks. The half-packet and quarter-packet row
processing loops were iterating columns 4 at a time starting from j2=0,
misindexing into the 8-column packed RHS buffer. This produced
completely wrong results for float GEMM when the number of rows was
smaller than the SIMD packet size (e.g. 2x10 * 10x8 float).

Add the missing nr>=8 column iteration blocks to both loops, matching
the pattern already present in the 3x, 2x, 1x, and scalar remainder
sections.
