Test component qualifier in shaders

Test component qualifier in shaders

Tests were added to verify that various combinations of component
qualifiers can be used with different data types (vec2, vec3, vec4,
ivec2 and ivec4) in following scenarios:

- in vertex shader input
- in fragment shader output
- when passing data from vertex shader to fragment shader

New tests:

dEQP-VK.glsl.440.linkage.varying.component.*

Components: Vulkan

VK-GL-CTS issue: 741
