[Keyboard] id80: Transpose matrix to use faster COL2ROW routines (#8930)
* id80: Transpose matrix to use faster COL2ROW routines Even the standard QMK matrix_scan() function can give about 2 times higher scan rate (if compiled with optimizations enabled) if the COL2ROW matrix layout is used instead of ROW2COL. Although the ID80 PCB is wired using the ROW2COL matrix layout, it is possible to transpose the matrix from the QMK standpoint, so that "columns" would correspond to horizontal connections, and "rows" would correspond to (mostly) vertical connections; in this case the matrix could be handled as if it had the COL2ROW layout. The matrix layout change makes the older VIA JSON layout definition incompatible, but the corresponding JSON was not yet accepted to the VIA repository, so it should still be safe to make this change. * id80: Remove obsolete comments

+ * optimizations, the difference in scan rate can be over 2 times). Because of
+ * this, the "columns" in the matrix layout now mostly correspond to physical
+ * rows, and the "rows" have mostly vertical physical orientation.
