[PATCH v5 3/7] configure: add --enable-qpl build option

[Yuan Liu <yuan1.liu@intel.com>]

add --enable-qpl and --disable-qpl options to enable and disable
the QPL compression method for multifd migration.

the Query Processing Library (QPL) is an open-source library
that supports data compression and decompression features.

The QPL compression is based on the deflate compression algorithm
and use Intel In-Memory Analytics Accelerator(IAA) hardware for
compression and decompression acceleration.

Please refer to the following for more information about QPL
https://intel.github.io/qpl/documentation/introduction_docs/introduction.html
