ethdev: increase flow type limit from 32 to 64

Increase the internal limit for flow types from 32 to 64
to support future flow type extensions.

Change type of variables from uint32_t[] to uint64_t[]:
rte_eth_fdir_info.flow_types_mask
rte_eth_hash_global_conf.sym_hash_enable_mask
rte_eth_hash_global_conf.valid_bit_mask

This modification affects the following components:
net/i40e
net/ixgbe
app/testpmd

ABI versioning used to keep ABI stability.
