This is the port of the vbdev compress logic into the accel framework. It includes just one enhancement, to only fill each mbuf in either src or dst array with max "window size" param to avoid QAT errors. Note that DPDK ISAL PMD was not ported as we have native ISAL compression in accel now. Note: ISAL w/DPDK is still built w/this patch, that can't be removed until the vbdev module moves to accel fw as it still depends on DPDK ISAL PMD. Follow-on patches will include addition C API for PMD selection, this patch just gets equivalent functionality going. Upcoming patches will also convert the vbdev compress module to use the accel framework instead of talking directly to compressdev. More patches will also address comments on vbdev common code that addressed here would make the review challenging. This patch also fixes a bug in the ported code that needs to be fixed here to pass CI. Capability discovery was incorrect causing all devices to appear to not support chained mbufs, with the mbuf splitting code this is important to get right.
