f9c0cf2a3a libcamera: MappedBuffer: Disable copy and assignment
MappedBuffers have a custom move constructor and assignment operator to
ensure that memory is not unmapped during object manipulation.

Because of the user-defined move constructor, the implicitly-declared
copy-constructor will already be deleted, however delete it explicitly
to help readability of the code, and make it clear that the object can
not be copied.

b3383da79f libcamera: buffer: Create a MappedBuffer
Provide a MappedFrameBuffer helper class which will map
all of the Planes within a FrameBuffer and provide CPU addressable
pointers for those planes.

The MappedFrameBuffer implements the interface of the MappedBuffer
allowing other buffer types to be constructed of the same form, with a
common interface and cleanup.

This allows MappedBuffer instances to be created from Camera3Buffer types.

Mappings are removed upon destruction.
