ATOM-15658 Better option of CreateCommonBuffer requires unique buffer name (#1133)

* ATOM-15658 Better option of CreateCommonBuffer requires unique buffer name
- Change the CreateCommonBuffer function to not require an unique  name by default.
- Remove the code for generating unique buffer names.
- Add buffer name to BufferAsset so it can be used for device object name instead of using asset file name.
- Change RPI::Buffer to use BufferName_AssetUuid as attachment id.
