Cleanup of planner code
- Use named axis indexes, `X_AXIS` etc. - Replace `block.steps_A` with block.steps[A]` - Replace `A_segment_time` with `segment_time[A]` - Add `A_AXIS`, `B_AXIS` for `COREXY` axes - Conditional compile based on `EXTRUDERS` - Add BLOCK_MOD macro for planner block indexes - Apply coding standards to `planner.h` and `planner.cpp` - Small optimizations of planner code - Update `stepper.cpp` for new `block` struct - Replace `memcpy` with loops, let the compiler unroll them - Make `movesplanned` into an inline function
