Too many places in the engine and the renderer expect texture names to
be insensitive: RAD files, material references, probably engine and game
calls too.
Make it universally case insensitive. Also, add rudimentary tests for
it.
Known issues:
- pbr materials are completely broken. They end up not being able to
find textures, seemingly due to memory corruption on materials side,
not textures.
- There are still places that try to get texture=1
Adds unordered_roadmap simple hash map:
- open addressing with linear probing
- size is fixed at init/compile time
- operates on an pre-allocated array of items with hashmap headers
Also adds basic tests for it.
And properly enables tests for ref_vk (i.e. alolcator)
