libcamera: camera: Simplify create() implementation

Browse source 
Now that the Camera class inherits from std::enable_shared_from_this, we
don't need to use std::allocate_shared anymore and can simplify the
Camera::create() implementation. This fixes compilation with recent
versions of libc++ whose std::allocate_shared implementation isn't
compatible with classes that are not publicly constructible.

The custom allocator is removed, but a custom deleter is needed as the
Camera destructor is private.
