Seungha Yang cf1286b0e9 d3d11: Add support for HLSL precompile and shader caching
Compile HLSL at build time in case of MSVC, and use it if device
supports shader model 5. Also cache/reuse pixel shader and vertex
shader objects.

# FIXME: Probably DXGIGetDebugInterface1 might be used on UWP app for development
# purpose. So, I suspect one possible reason why WACK is complaining about
# DXGIGetDebugInterface1 is that debugging APIs couldn't be used for
# Windows store app, but couldn't find any reference about that.

# [IDXGIDebug1]
# https://docs.microsoft.com/en-us/windows/win32/api/dxgidebug/nn-dxgidebug-idxgidebug1
# is saying that the IDXGIDebug1 interface is available for both desktop app and
# UWP. And then the *DXGIGetDebugInterface1* method need to be called to obtain
# the IDXGIDebug1 interface.
#
# [DXGIGetDebugInterface1]
# https://docs.microsoft.com/en-us/windows/win32/api/dxgi1_3/nf-dxgi1_3-dxgigetdebuginterface1
# is mentioning that DXGIGetDebugInterface1 is desktop app only.

# PLEASE LET US KNOW A CORRECT WAY TO OBTAIN IDXGIDebug1 ON UWP, MICROSOFT
