AdvancedColorImages sample doesn't build

[Gavin-Williams]

I get the following errors

C2144 syntax error: 'IDXGIAdapter4' should be preceded by ';' AdvancedColorImages C:\Program Files (x86)\Windows Kits\10\Include\10.0.20348.0\shared\dxgi1_6.h 52

C4430 missing type specifier - int assumed. Note: C++ does not support default-int AdvancedColorImages C:\Program Files (x86)\Windows Kits\10\Include\10.0.20348.0\shared\dxgi1_6.h 52

Also, Intellisense is showing an error at line 144 of AdvancedColorImages.cpp

m_winComp = new WinComp(); // object of abstract type WinComp is not allowed

I'm not as familiar with this sample, but it looks like something may have changed with the bundled version of cppwinrt in that version of the SDK. I had to make two changes to get this to compile:

Hopefully that gets you unblocked for now.
