target/arm: Fix SME full tile indexing

For the outer product set of insns, which take an entire matrix
tile as output, the argument is not a combined tile+column.
Therefore using get_tile_rowcol was incorrect, as we extracted
the tile number from itself.

The test case relies only on assembler support for SME, since
no release of GCC recognizes -march=armv9-a+sme yet.
