Ivan AvdeevandGitHub a251600c8a engine: common: imagelib: add KTX2 support (#1455) 
* engine: common: imagelib: add KTX2 support

Adds basic KTX2 support for a few compressed formats. KTX2 essentially
is a Vulkan-centric texture format that supports literally hundreds of
pixel formats.
For now only support for these is added:
- `VK_FORMAT_BC4_UNORM_BLOCK`
- `VK_FORMAT_BC4_SNORM_BLOCK`
- `VK_FORMAT_BC5_UNORM_BLOCK`
- `VK_FORMAT_BC5_SNORM_BLOCK`
- `VK_FORMAT_BC6H_UFLOAT_BLOCK`
- `VK_FORMAT_BC6H_SFLOAT_BLOCK`
- `VK_FORMAT_BC7_UNORM_BLOCK`
- `VK_FORMAT_BC7_SRGB_BLOCK`

Adding more formats is relatively straightforward:
- Copy format definition from `VkFormat` enum in `vulkan_core.h`
- Add a new definition into `pixformat_t` enum.
- Add format size calculation into `Image_ComputeSize()`

While we're at it, also adds a few new formats to DDS:
- BC4_UNORM -- PF_BC4_UNSIGNED
- BC4_SNORM -- PF_BC4_SIGNED
- BC5_UNORM -- PF_BC5_UNSIGNED
- BC5_SNORM -- PF_BC5_SIGNED
- BC7 is expanded into BC7_UNORM and BC7_SRGB

ref_gl and ref_soft code is updated where it made sense. But not tested
really. Support for these formats has been tested with ref_vk.

* address spaces-vs-parentheses formatting where noticed

* parenthesize sizeofs

* move ktx2.h to imagelib as img_ktx2.h; massage it a bit

* use SetBits() instead of |=

* remove stale TODO comments

Alibek Omarov 1caa276531 engine: common: imagelib: fix loading cubemaps 
Loop break was a bug that was added after refactoring imagelib loader.

In fact, it was mindlessly copypasted from old code, where same break was
used to quickly exit from inner format bruteforcing loop, than outer cubemap
loading loop.
