Rework synchronization

[SaschaWillems]

This is a second attempt to rework synchronization for all samples. The goal is to get rid of the vkQueueWaitIdle at the end of each frame and introduce frames-in-flight. This PR will also do away with pre-building command buffers.

Note: This is a Work-in-progress and far from finished. Even the samples that have been updated may exhibit issues as some parts of the framework (like the UI) haven't been adjusted yet.
