GPU: Swap bindings array instead of copying (#4003)
* GPU: Swap bindings array instead of copying

Reduces work on UpdateShaderState. Now the cost is a few reference moves for arrays, rather than copying data.

Downside: bindings arrays are no longer readonly.

* Micro optimisation

* Add missing docs

* Address Feedback
