(#20335) eudev: Add recipe

* eudev: Add recipe

* Set pkg_config_name to libudev

* Enable libblkid

* Specify requires and use consistent option name with_selinux

* Bump to the latest version

* Fix compatibility of the pkg-config file

Set the version for pkg-config properly and set exec_prefix.
This maps to version checks for libudev.

* Bump version

* Add PkgConfigDeps to test package

* Convert version to string

* Fix version for Conan V1

* Save version of libudev to a file for package_info

* Bump linux-headers-generic to 6.5.9
