Updated AnimNode registration in LyShine and Maestro to register to a member variable map (#6786)

* Updated the Maestro MovieSystem and LyShine AnimationSystem to register
Anim Nodes and Anim Params into a member variable map

Previously the registration was occuring in a global variable map inside
of Movie.cpp and UiAnimationSystem.cpp

Rolled back the changes to update the CUiAnimNode and CAnimParamType to
use the stateless allocator in their m_name string member.
This was only needed because those types were used in global memory.

* Updated the AZStd::hash specializations for basic_string and
basic_fixed_string to be transparent.

This allows hashing of types that aren't basic_string or
basic_fixed_string using the hash specializations for those types
without needing to create an instance of those types.

* Adding call to disable saving of the UserSettings.xml in the DisplaySettingsPythonBindingsFixture to avoid race condition running the test in parallel
