opencl: enable the general fp mm for non-cont input and as a fallback for specialized kqv kernel for adreno (#18970)
* opencl: add `copy_to_contiguous` and utilize mm kernels
* opencl: only copy to cont for f32 and f16 tensors
* opencl: use cont mm for fallback when dst is large
* opencl: use nb local to copy-to-cont
* opencl: use local offset as well
