Direct conversion helpers for quaternion to the scaled axis-angle representation and back without the need to convert them first to the axis-angle format and manually scale (or normalize on the way back). This also avoids having to deal with the special case of an identity representation which is 0,0,0 in the scaled axis-angle format while our convention for axis-angle is 0,1,0 for the axis and 0 for the angle.
Added unit tests that check the conversion round-trips from quaternion -> (scaled) axis-angle -> quaternion as well as comparing the scaled axis-angle representations from the direct helper functions as well as the axis-angle while manually scaling/normalizing.

The SettingsRegistryMergeUtils.cpp now supports specifying a path to a JSON Merge Patch formated settings registry file via the --regset-file option.
The option supports specify an anchor key to merge the settings underneath that is separated from the filepath via "::"
Ex. `--regset-file="Registry/custom.setreg::/Custom/Anchor"`
An AZ::Console command of "sr_regset-file" has also been added to allow merging of a setting registry file as well.

AZStd::fixed_vector had all its functions marked with constexpr, but this requires all member variables to be fully initialized. This meant that the internal array used to store elements always has to be fully initialized. This was done for trivial classes but not for non-trivial classes. As a result trivial classes always did a memset (or more optimized versions for smaller buffers) while the non-trivial version couldn't actually be stored in a constexpr variable. Since AZStd::fixed_vector is meant to be dynamic the choice was made to remove the constexpr from all non-static member functions in favor of avoiding the overhead of memset, which profiling showed was a considerable overhead depending on the reserved size. If a truly constexpr array is needed than AZStd::array is a better choice as that's designed to not by dynamic.

Replaced and removed the CryTimer (gEnv->pTimer). The new TimeSystem is a merger of the current time functionality found in the engine.
* Rename TimeSystemComponent.h/.cpp to TimeSystem.h/.cpp
* Adding New TimeSystem
* remove old timer cvars
* small improvements to the time system.
- updated parts to use the time conversion functions.
- in AdvanceTickDeltaTimes applying t_simulationTickScale is now uses doubles instead of floats.
* Replace gEnv->pTimer / ITimer usages with TimeSystem
* Updating usages of AZ::TimeMs{ 0 } and AZ::TimeUs{ 0 } to AZ::Time::ZeroTimeMs and AZ::Time::ZeroTimeUs
* red code the CryTimer
* using TimeUs instead of TimeMs is some cases + updating usages of old cvars to new

This change adds a `DomBackend` interface and a `DomBackendRegistry` for backend discovery (currently not hooked up to anything) alongside a JSON backend implementation.
The JSON backend comes with a small suite of unit and performance tests. The unit tests validate generic DOM conversion to and from serialized JSON and rapidjson::Document objects (the support for which lives in `JsonSerializationUtils.h`).
The performance tests show a throughput decrease compared to directly using the rapidjson serializer when mirroring our current pattern of copying strings from the serialized JSON representation, but with the coming in-memory store we have the opportunity to keep the buffer in memory and deserialize in-situ using rapidjson's API, which is consistently at least 100MiB/s faster on my machine (Ryzen Threadripper 3970X). The first parameter is the nested object complexity (N*N, objects with N keys comprised of arrays with N values) and the second parameter is the base size of the strings within each entry of this object.

For `AZ::DOM::Document`, the current plan is to offer helper methods that can load from a file path or string using a given backend that can take advantage of in-place parsing by internally storing the serialized buffer.

* Enable relocation of the Project Game Release Layout
Relocating the Project Game Release Layout to another directory on the file system failed due to the querying of the engine root failing due to the ComponentApplication::m_engineRoot not using the project path stored in the SettingsRegisry if the engine root cannot be detected
Removed the ApplicationRequestBus GetEngineRoot function.
The ComponentApplicationRequestBus has a function of the same name that returns the same path.
Removed the deprecated GetAppRoot function.
The path it returns has no defined value. It was not the engine root or the project root.
Removed unused CFileUtil and CFileUtil_impl functions that were invoking the ApplicationREquestBus GetEngineRoot function.
On the way to update the functions it was discovered that they aren't called
Added a CalculateBranchToken overload that can populate a fixed_string to avoid heap allocations
