Fix D3D12 debug crash due to validation layers SDK bug (#3222)

Browse Source 
* Fix D3D12 debug crash due to validation layers SDK bug

* Change LONG to FARPROC to be technically correct

* Make requested changes:
Move windows version checking to function in bgfx.cpp
Change windowsVersionIs to also use this technique
Use bgfx code style
Specify dwOSVersionInfoSize prior to calling rtlGetVersion

* Merge both functions into one
Use bx::dlsym instead of GetProcAddress directly
Fix major & minor comparison logic

* Fix win10 version comment

* Revert rendererCreate check back to Win 0x0602

* Clean up logic as per suggestion
