[DOCS] Move the o3de repo wiki page content to the documentation website

[guillaume-haerinck]

Describe the issue briefly

The o3de github repo provides a good wiki section with information that is not currently available on the O3DE website. Things such as :

• Using the CPU or GPU profiler
• Shader compilation
• IDE setup
• Exporting LUA symbols to an external IDE
• etc

I believe this wiki should be nuked and all of its content moved to appropriate pages, so that there is always a single source of truth, and that these section can be discovered more easily when looking for them (searching for o3de profiler on google does not return anything)

Which page(s) / section(s) are affected?

Too many to list them all

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

Yes with sig-graphics, sig-core and maybe sig-content. While it is possible to just copy-paste the actual content, it might be the opportinity to refresh some of it with images and so on, and would need to be double checked by engineer of the sig listed
