Precision verification in CLI

-Added an option to compare VkFFT to cuFFT (if enabled) and FFTW in single, double and half precision. Launch with -vkfft and keys 11-13
-Path to FFTW can be specified in CMakeLists
-Reverted TLB fix for AMD GPUs. Apparently, they can't handle more than 64-128 buffers bound. Multiple buffer input/outputs works
-Added include guards and static definitions
-All files under MPL 2.0 license are moved to the vkFFT folder
-This version should be stable and has most of planned features, so it is released as 1.1.0
