With armv8-neon being enforced for all ARM based machines, running
any libcamera app on raspberrypi (e.g. Raspberry Pi B Rev 2) results
in Illegal Instruction.

To fix this, set armv8-neon for 32bit raspberrypi3 and raspberrypi4
but defaults to TARGET_ARCH for other non-aarch64 machines.

The 'opencv' PACKAGECONFIG entry was missing the build dependency.

Add a 'drm' PACKAGECONFIG entry in order to provide support for a
DRM preview window while running the libcamera apps.

The 'tensorflow-lite' PACKAGECONFIG entry was missing the corresponding
build dependency. In order to be consistent with the build macros,
replace the feature with a 'tflite' package config entry.

Even though the libcamera apps are a rewrite of the rpicam apps and
maintained by the raspberry folks, switching to libcamera makes the
code hardware agnostic and thus could be compiled and used on various
machines featuring a camera device supported by a libcamera pipeline.

For this reason, do not enforce COMPATIBLE_MACHINE.

The libcamera-apps project is written in a hardware-agnostic manner
thanks to libcamera, and thus isn't specific to the rpi SoC family.

Moreover, the project is correctly named libcamera-apps and not
rpi-libcamera-apps, so rename the recipe in order to reflect that.

Move the libcamera-apps recipe to dynamic-layers/multimedia-layer
alongside with its libcamera dependency.

Bump libcamera to 3d9ac10 to get a fix for the current libcamera from
meta-openembedded/meta-multimedia for the following issue:

    error: 'StreamRoles' in namespace 'libcamera' does not name a type; did you mean 'StreamRole'?
       55 |         using StreamRoles = libcamera::StreamRoles;
          |                                        ^~~~~~~~~~~
          |                                        StreamRole

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.

Now that the libcamera package from meta-multimedia has support
for flicker controls and libcamera-apps uses meson, we can bump the
package to its latest revision.
