vo_opengl: add support for vulkan GLSL dialect

Redefining texture1D / texture3D seems to be illegal, they are already
built-in macros or something. So just use tex1D and tex3D instead.

Additionally, GL_KHR_vulkan_glsl requires using explicit vertex
locations and bindings, so make some changes to facilitate this. (It
also requires explicitly setting location=0 for the color attachment
output)
