DepthwiseConvolution changes to enable fp16 in armv8a multi_isa builds

* Changes in filelist.json moving fp16 file from common to fp16 attribute

* Removed the guard __ARM_FEATURE_FP16_VECTOR_ARITHMETIC in
  CpuDepthwiseConv2dAssemblyWrapperKernel to always create the assembly
  kernel

* Partially resolves MLCE-1102
