Updated all array_view uses with the C++20 span. (#7157)

Browse Source 
* Updated all array_view uses with the C++20 span.

The updates were done in the following order
1. `AZStd::array_view<([^>].+)\* ?>`  -> `AZStd::span<\1 const>`
2. `AZStd::array_view<(?:const )(.+)>` -> `AZStd::span<const \1>`
3. `AZStd::array_view` -> `AZStd::span`

Removed the implementation of array_view.

* Added missing whitespace between `const` and the typename for spans.

Updated the ShaderTest comparison of the ShaderResourceGroupLayout span
to compare the sizes as well

Updated comments on some of the methods that stated that they return "an
array" to mention they return "a span".
