apps: Add ipa-verify application
When packaging libcamera, distributions may break IPA module signatures if the packaging process strips binaries. This can be fixed by resigning the modules, but the process is error-prone. Add a command line ipa-verify utility that tests the signature on an IPA module to help packagers. The tool takes a single argument, the path to an IPA module shared object, and expects the signature file (.sign) to be in the same directory. In order to access the public key needed for signature verification, add a static function to the IPAManager class. As the class is internal to libcamera, this doesn't affect the public API.
