Add debug utilities for Vulkan

Features:
- Debug-only tracking of objects by type. See
get_driver_allocs_by_object_type et al.
 - Debug-only Breadcrumb info for debugging GPU crashes and device lost
 - Performance report per frame from get_perf_report
- Some VMA calls had to be modified in order to insert the necessary
memory callbacks

Functionality marked as "debug-only" is only available in debug or dev
builds.

Misc fixes:
 - Early break optimization in RenderingDevice::uniform_set_create

============================

The work was performed by collaboration of TheForge and Google. I am
merely splitting it up into smaller PRs and cleaning it up.
