wifi: iwlwifi: prepare for reading TAS table from UEFI

Browse Source 
We are going to support reading BIOS tables from UEFI
too, Refactor the TAS table flow:

1. Rename and move the common code to the regulatory.h/c files.
2. Remove the IWL_TAS_BLOCK_LIST_MAX, as we can use IWL_WTAS_BLACK_LIST_MAX
   instead.
