[DOCS] Need Documentation for Math Functions and Types in Lua Scripting

[santorac]

Describe the issue

There are many functions and data types reflected in MathReflection.cpp but this is not documented under https://www.o3de.org/docs/user-guide/scripting/lua/

The page should document

• all functions reflected by "void MathReflect(BehaviorContext& context)" like "Sin", "Cos", etc.
• all types reflected by "void MathReflect(ReflectContext* context)" like "Vector3", "Quaternion", etc.
• all functions in all types mentioned above. For example, see "void Vector3::Reflect(ReflectContext* context)"

Impacted page(s)

New page under https://www.o3de.org/docs/user-guide/scripting/lua/

Does this work have an engineering dependency? What is it?

Yes. Needs information from respective SIG that owns Lua and scripting content, possibly @o3de/sig-core.

[santorac]

I am creating a placeholder page called math-library.md in the development branch.

I updated the issue description as this is technically a feature request, not a docs issue.

We also need assistance with authoring this page from @o3de/sig-core.

Also, a placeholder of this page was created in #1720. Here's a preview of page: https://o3de.org/docs/user-guide/scripting/lua/math-library/
