Use arrays & generate loops for TE LUT tables

[tomalin]

As a future improvement, the LUT-related signals in SectorProcessor.vhd, such as TE_L1PHIC12_L2PHIB10_bendinnertable_addr should be declared in an array with enum index, such as TE_bendinnertable_addr(L1PHIC12_L2PHIB10). And the instantiation of the "work.tf_lut" done inside "generate" loop. This will make the VHDL more compact.
