Optimize SetUniform for isFloat16 case Before this change, we use a temporary std::vector<GLshort> to store the transformed GLshort uniform data. This incurs heap memory allocation and deallocation every time we call SetUniform(). This change removes the temporary std::vector<GLshort>, and use the stack memory to store the transformed GLshort uniform data. To make code easier to read, placing the UpdateBufferWithLayout() function for the special GLshort case inside the SetUniform() itself, and remove the UpdateBufferWithLayout implementation for GLshort type. On Pixel 9, the driver_overhead_2 trace wall_time changes from 9.4 ms to 8.7 ms after this change.
