Remove duplicated test groups

Remove duplicated test groups

While adding support for dynamic rendering to renderpass group
a mistake was made that added 3 groups with the same tests to both
renderpass2 group and legacy renderpass group.

This mistake was fixed on 1.3.1 branch but is present on 1.2.8
and 1.3.0. There is no need to execute same tests twice - this
change removes duplicates. This fix should be propagated only to
1.3.0.

Components: Vulkan

VK-GL-CTS issue: 4225

Removed tests:
dEQP-VK.renderpass.depth_stencil_resolve.*
dEQP-VK.renderpass.fragment_density_map.*
dEQP-VK.renderpass2.multiple_subpasses_multiple_command_buffers.test
