Otherwise, counter gets crazy when watchdog resets the swcore and feeds all the endpoints and NIC with ack=1.

This way one Tx OOB word may be lost, and tx timestamp won't be generated causing _wrn_start_xmit: descriptor overflow: tx timestamp pending_ message from wr-nic driver

- removed declarations of unused signals - reduced padding_size to bits needed for padding possible runt Ethernet frames - simplified signal assignments and conditions in FSM (e.g. no need to check if needs_padding = 1 and padding_size /= 0, because when former is true, the latter is always true too) - moved assignment of outputs validated with other outputs outside FSM to simplify the logic (fake rtu decision)

- removed ARB_DISABLED state, instead FSM is hold in ARB_START_SCAN unless module is enabled - removed declarations of unused signals (granted_desc_idx, desc_idx_d0, check_count, stupid_hack) - moved assignment of outputs validated with other signals outside FSM to simplify the logic (txdesc_current_o/rxdesc_current_o are validated by desc_grant_o, and stored in internal registers of nic_rx_fsm and nic_tx_fsm) - rewritten ARB_WRITE_DESC state, so that data output is driven by desc_subreg counter instead of separate counter in case statement. - more exotic regnums in marshalling functions (nic_descriptors_pkg) to minimize logic required to output correct data when needed in modified ARB_WRITE_DESC state

Just a cleanup to have all subprobrams the same type (functions) in the package.

[switch-optimization]: wrsw_nic/nic_elastic_buffer: use native almost_full and almost_empty for generating stall Xilinx FIFOs have native almost_empty and almost_full outputs driven at configured thresholds. Using them saves few LUTs comparing to stall generation based on usedw counter as it was done earlier.

It's just a trivial clean up commit, it does not save any resources.
