* 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

Remark: the gem file PassTemplates.azasset was renamed and will be connected via code in the future to avoid the need to declare in the global pass template.

ATOM-16273 Compiling SceneSRG before updating it can cause a gpu crash
Changes include:
1. Removed Scene::SetShaderResourceGroupCallback() function and clean up code which use this function.
2. Moved SceneTimeSrg.azsli to RPI's DefaultSceneSrg folder and setup the constants in RPI::Scene
3. Add AZ::Event for Scene's update srg event which features and update scene srg at proper place
4. UpdateTransformServcie FP to use PrepareSceneSrg event handler.
5. Clean up shaders and srgs used in project templates.

* Final update copyright headers to reference license files at the repo root

* Fix copyright validator unit tests to support the stale O3DE header scenario
Signed-off-by: spham <spham@amazon.com>
Updated AzFramework::Scene to allow it to serve as the one-stop location for localized singletons. Localized singletons in this case are instance that can only occur once in an environment but multiple times within an application. As an example, this allows settings up a single camera per viewport for instance.
Highlights of changes:
Replaced the original ebuses with interfaces and events for easy of use and performance.
Removed the Entity Context specific code and moved that to new locations within the Entity Context itself.
Allowed basic inheritance. If a subsystem isn't found in a scene the parent can optionally be searched.
Scenes can enter a zombie state and avoid immediately being deleted. This is needed for situations where subsystems can't be destroyed until async calls have been completed.
