Refactor large test groups

Refactor large test groups

Large test groups were split into smaller groups. Undescriptive
groups and cases were renamed to better represent their function.

dEQP-VK.api.buffer.*
- VK_BUFFER_USAGE_INDIRECT_BUFFER_BIT is listed in the array of
  possible buffer usage modes but is never actually used.
  Test cases using said mode were added.

Affects:

dEQP-VK.api.buffer.*
dEQP-VK.pipeline.vertex_input.*
dEQP-VK.api.buffer_view.create.*
dEQP-VK.api.image_clearing.clear_color_image.*
dEQP-VK.texture.filtering.*
dEQP-VK.ubo.*

Components: Vulkan
