qcacmn: Featurization of DP_TX_EXT_DESC_POOL_OPTIMIZE

Browse Source 
This flag DP_TX_EXT_DESC_POOL_OPTIMIZE if enabled will reduce the number
of ext tx desc pool to 1.

1. Changes done to split the tx_desc and ext_tx_desc pool number
variables in alloc and free path. Based on this flag the reduced
ext_desc_pool count will be returned.

2. In Tx path, since the pool id is selected based on the CPU, changes done
to override the desc_pool_id of ext_desc_pool via new API
dp_tx_ext_desc_pool_override to 0 with which from whatever core the packets
comes from, pool 0 will be chosen for ext_desc.
