Adopting the dynamic implementation of DMRS at the gNB side

Browse Source 
- Using the implemented DMRS functionalities at the MAC layer at the gNB side
  - Removing is_dmrs_symbol function
  - Temporary implemetation at the UE side considering DMRS symbol is at the 1st PUSCH symbol,
    until the nFAPI structs for DMRS is adopted at the UE side
