Update PhysDeriv CUDA kernel implementation

Issue/feature addressed

This MR tidy-up PhysDeriv CUDA kernels in prevision of future benchmarking tests

Here are a summary of the changes:

• Tidy-up PhysDeriv CUDA kernel implementation
• Fuse kernel functions for better efficiency
• Simplify loops in kernel functions
• Improved coalesced memory access to global memory
• Add templated option for shared memory
• Add 1D indexing version of QP (multilevel) Kernels
• Interleave data for non-QP kernels

To do (future MRs):

• Interleave data for non-QP kernels
• Consider templating nq0, nq1, nq2 parameters
• Optimizing CUDA grid parameters
