libcamera: device_enumerator_udev: Use std::string_view
In `udevNotify()`, constructing an std::string from the device's associated action is unnecessary as it is only compared against static strings, and for that purpose an std::string_view works just as well, while being cheaper to construct. In the same vein, an std::string_view can be used to store the device's devnode initially, and the string construction can be deferred until it is needed. Furthermore, previously `udev_device_get_devnode()` was called twice. The extra call is now removed.
