8356860: Use common Graphics Root Signature in NativeShader

- NativeShader code got vastly simplified because its code creating Root
  Signatures was removed and common Graphics RS was used instead
  - No JFX Prism/Decora Shader used more than 4 textures, which is the
    same as common Graphics RS was already set to process. This greatly
    simplified the transition to common RS.
  - ShaderSlots were renamed to better reflect which Root Signature
    indexes are used.
  - ShaderCommon.hlsl is now added as an include directory when building
    JSL-created Prism/Decora shaders.
- Adjustments to backend to accommodate common Graphics RS
- Minor adjustments to fix some older missed mistakes
  - NativeTexture's SRV is now created only for non-depth Textures and
    its ViewDimension is adjusted for MSAA Textures
  - RingContainer no-checkpoints assertion has been removed - when
    loading larger textures it triggered. Warning log remains to
    potentially detect those situations when performance matters more.
