* Added new helper functions to get the shortest equivalent of the rotation. In case the w component of the quaternion is negative the rotation is > 180° and taking the longer path. The quaternion will be inverted in that case to take the shortest path of rotation.
* Added unit test.
* Renamed the angle parameter of the CreateRotationX/Y/Z() functions into angleInRadians.

Sleeping in tests and attempting to rely on fine-grained measurements to
check code validity is intrinsically brittle. Wall-clock time is
unreliable in an environment where tests are run under a hypervisor that
may choose to suspend your VM at any point, or in situations where the
OS cannot schedule your thread in time. The correct way to reintroduce
these tests in the future is provide an override for the timestamp
queries that can be injected in the test environment to control the wall
time deterministically.

In some cases, the interface being queried may be persistently nullptr
(e.g. a gem isn't active, or a feature was disabled by a cvar). In this
case, querying the interface would always enter the writer-lock branch
with existing code because nullptr was synonmous with "we haven't
queried for this variable yet."
This PR adds an additional state variable that is set when s_instance is
assigned to, so that after the variable is queried and found to be null,
future queries can enter the read-lock branch.

- Use a vector for shared string storage (to avoid the double heap allocation for AZStd::string)
- Use a shared heap allocated any for opaque types (instead of an unsafe ref)
- Add a string comparison key lookup benchmark to measure the impact of Name

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.
