Ben Clayton 1a1b5278d5 tint/transform: Inline HLSL uniform / storage buffers
Change the DecomposeMemoryAccess to behave more like the DirectVariableAccess transform, in that it'll inline the access of buffer variable into the load / store helper functions, instead of passing the array down.

This avoids large array copies observed with FXC, which can have *severe* performance costs.

Fixed: tint:1819
