D3D11: Minor optimizations to Renderer11.

This moves the skipDraw logic into applyPrimitiveType, since it's more efficient to only check the primitive type once. Also merges the draw*Impl and genericDraw* methods, since the generic* methods weren't really doing anything anymore, and all the state logic lives in StateManager::updateState. This series of small optimizations gives about a 15% improvement on the draw call benchmark for the D3D11 backend with the null driver.
