Hair and Tools Pipeline bug fixes (#4902)
- Fixed fallback connections for hair pipeline to allow disabling the parent pass hierarchy when not required
- Renamed the Thumbnail pipeline to be used as generic minimal tools pipeline
- Reused the Tools pipeline for the preview renderer - minimal FPs and passes

Remark:
- The tools pipeline should have folloup submits for reducing passes to minimal required render passes

Hair - Hair Gem introduction to O3DE from Atom/barlev/AtomTressFX_DevRebase (#4439)
* Hair
- First introduction of Hair gem to Atom and O3DE
- The hair technology is based off TressFX 4.1
- These are some of the areas we enhanced the original TressFX implementation:
   - Lighting model was replaced and we now use a modified Marschner model
   - Blending is done directly with the back buffer removing the silhouette of the original implementation
   - Hair depth / thickness is now calculated to remove incorrect back lighting (TT lobe in the Marschner model)
   - Thickness corrected to handle hair gaps hence introducing better light passage for the TT
   - The hair is fully integrated into the Atom pipeline and structure design
   - Usage of single shared buffer for the computer buffers reduces barriers sync overhead

Remarks:
- Collisions via SDF compute are to be introduced soon
- Improved shortcut rendering method ala Eidos Montreal to be introduced soon
