fix(rendering): bottom side orientation

- Fix bottom side texture orientation to not flip texture. Special
  thanks to @GregoriusT who raised awareness of potential issue with
  texture where direction matters (like button panels or texts).
- Implement a flipped bottom texture rendering to have ore blocks
  use the very same orientation as dumb blocks ore textures from other mods.
- Refactor GT_SidedTexture to use GT_RenderedTexture for rendering,
  rather than duplicate the rendering code of it.
