[PATCH v6 3/7] configure: add --enable-qpl build option

[Yuan Liu]

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

For more live migration with IAA, please refer to the document
docs/devel/migration/qpl-compression.rst
