Revert of Refactor how we store and use samplers in Ganesh (patchset #7 id:120001 of https://codereview.chromium.org/1885863004/ )

Original issue's description:
> Refactor how we store and use samplers in Ganesh
>
> The main goal of this refactorization is to allow Vulkan to use separate
> sampler and texture objects in the shader and descriptor sets and combine
> them into a sampler2d in the shader where needed.
>
> A large part of this is separating how we store samplers and uniforms in the
> UniformHandler. We no longer need to store handles to samplers besides when
> we are initially emitting code. After we emit code all we ever do is loop over
> all samplers and do some processor independent work on them, so we have no need
> for direct access to individual samplers.
>
> In the GLProgram all we ever do is set the sampler uniforms in the ctor and never
> touch them again, so no need to save sampler info there. The texture access on
> program reuse just assume that they come in the same order as we set the texture
> units for the samplers
>
> For Vulkan, it is a similar story. We create the descriptor set layouts with the samplers,
> then when we get new textures, we just assume they come in in the same order as we
> set the samplers on the descriptor sets. Thus no need to save direct vulkan info.
