fix(vulkan): implement MirrorOnceClampOGL wrap mode

Adds support for wrap mode 7 (MirrorOnceClampOGL) in the Vulkan renderer's
WrapMode function. This mode is mapped to VK_SAMPLER_ADDRESS_MODE_MIRROR_CLAMP_TO_EDGE
as Vulkan doesn't have a direct equivalent to OpenGL's GL_MIRROR_CLAMP.

Fixes assertion failure: "Unimplemented wrap mode=7"
