feat(users/flokli/ipu6-softisp): init r/7454

This code adds support for the ipu6 webcams via libcamera, based on the work in
https://copr.fedorainfracloud.org/coprs/jwrdegoede/ipu6-softisp/.

It's supposed to be included in your NixOS configuration imports.

+Subject: [PATCH 02/25] libcamera: internal: Move dma_heaps.[h,cpp] to common
+ directories
+
+DmaHeap class is useful outside the RPi pipeline handler too.
+
+Move dma_heaps.h and dma_heaps.cpp to common directories. Update
+the build files and RPi vc4 pipeline handler accordingly.
