Add new sample for VK_EXT_host_image_copy

[SaschaWillems]

Description

This PR adds a new sample for the VK_EXT_host_image_copy. It shows how to replace traditional image staging with host image copies and also comes with a tutorial on how to use this extension.

I have tested the sample on Windows 11 with an nvidia RTX 4070.

Fixes #1076

• [x] I have tested the sample on at least one compliant Vulkan implementation

The sample runs fine for me, just a few minor comments on the documentation.
