libcamera: MappedBuffer: Disable copy and assignment

Browse source 
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.
