Big performance update

-Solved most nonstrided shared memory conflicts with new on-fly axis swapping technique
-Improved R2C/C2R performance. Will add odd sequence lengths in the next update
-Improved register management for large primes
-Added rocFFT benchmark and precision scripts
-Added new benchmarks: 1000 - tests all 1D FP32 systems from 2 to 4096, 1001 - tests all 1D FP64 systems from 2 to 4096, 1003 - tests all 3D FP32 cube systems from 2 to 512 for VkFFT/cuFFT/rocFFT. Will update plots soon
-Switched to dynamic shared memory allocation in CUDA and HIP backends
-Bugfixes to strides definition and buffer layout management
