Remove camera locking API

QCamera::lock()/unlock() is something that's not needed
these days anymore. cameras will automatically focus anyway,
there's no real reason to lock the focus (or other properties)
to some specific value in 99% of the cases.

Plus it wasn't supported on Linux or macOS/iOS anyway.
