ComposerClient[Writer/Reader]: enforce a specific display

Add a new parameter and member to ComposerClient[Writer/Reader]
representing the only display it should apply to. The caller is
responsible for ensuring that they only ever refer to that same display.
The display is recorded here for error checking. This isn't strictly
necessary, but crashing here verifies that we only use the proper
display.

This is helpful for use with DisplayCapability.MULTI_THREADED_PRESENT,
although it is fine to use a single display per writer/reader without
the capability.

For the Reader, make the display optional, so that a single reader can
continue to be used for multiple displays. This allows devices without
the new DisplayCapability to continue to work without changes.

Remove copy constructor and operator=. Add a move constructor. This
ensures it will be properly moved when used in containers.
