dpdk: Add additional CPU ISA detection strings

Browse Source 
This commit enables OVS to at runtime check for more detailed
AVX512 capabilities, specifically Byte and Word (BW) extensions,
and Vector Bit Manipulation Instructions (VBMI).

These instructions will be used in the CPU ISA optimized
implementations of traffic profile aware miniflow extract.
