meson: Set a SONAME version in the libcamera libraries

Browse source 
The libcamera and libcamera-base libraries are currently unversioned, but
donwstream users expect these to have a proper SONAME version in order to
package them.

A stable release has not yet happened because the project is still under
development and the API/ABI might change. But having a versioned SONAME
would allow distributions to package libcamera, without the need to add
any downstream patch to set the version.

Since the "0.0.0" version is already used in different places, let's also
use that as the library version. The meson build system will use the first
part of the version ("0") as the SONAME version, which is aligned with the
convention used by other projects:

$ ls /lib64/libcamera*so* -1
/lib64/libcamera-base.so
/lib64/libcamera-base.so.0
/lib64/libcamera-base.so.0.0.0
/lib64/libcamera.so
/lib64/libcamera.so.0
/lib64/libcamera.so.0.0.0

$ objdump -p /lib64/libcamera.so.0.0.0 | grep SONAME
  SONAME               libcamera.so.0
