Move some Device methods to private section (#16259)

### Ticket
None

### Problem description
There are plenty of Device methods which are only used by device itself
but they are in a public section

This PR depends on #16256

### What's changed
This PR does not add any new functionality, nor changes existing. It
shuffles things around.
* Moved near every method thats only used by Device to the private
section (19)
* Re-groupped methods logically: methods that proxy to allocator, to
cluster
* Moved a couple implementations to cpp
* Reviewed usage of some methods, left comments where its desirable to
review usage with owners
* Removed template where it was not used

Whats next:
* Discuss and align what we can/want to do about the two outlined groups
of methods
* Review notes with owners, align on next steps
