libcamera-apps: switch from CMake to meson

Browse Source 
CMake is removed in upstream libcamera-apps as of 9e17265,
thus switch to meson to build the package from now on.

Add PACKAGECONFIG entries and neon flags matching the settings
project meson.build as described in the official documentation
https://www.raspberrypi.com/documentation/computers/camera_software.html#building-libcamera-apps

Default to "drm" for PACKAGECONFIG as it is the only option enabled
in both recommended meson setup for Raspberry Pi OS and Raspberry Pi
OS Lite.
