Merge remote-tracking branch 'origin/oran_fhi_f_dpdk_21_plus' into integration_2025_w28 (!3504)

Improvements to the FHI for enabling further use cases These changes to the FHI were primarily thought to enable the integration of the intel ACC ( !3344 ) in parallel of the FHI. I preferred to make a separate MR because I believe this topic is orthogonal enough to be handled separately and because I wanted to bring even further improvements. The improvements that it actually brings are: - Enable compiling and running xran F release with DPDK 21+ - Enable including a BBDEV device in addition of the ethernet device for the FHI when performing EAL init, which is necessary for using the intel ACC with the FHI. - Fix an issue in usage of pkgconfig in xran E and F release. This enables to reliably build xran with the version of DPDK requested to pkgconfig while before this fix xran was always selecting the headers installed in /usr/local.
