This reverts commit ee9ee634.

Reason for revert: Likely broke remoting tests on Win7, https://crbug.com/875619

Original change's description:
> [Windows Host] Prevent connection hang for hosts with 3D Display Mode enabled
> 
> This change prevents a hang when connecting to a Windows machine
> which has curtain mode and 3d display mode enabled.  The root cause
> of the hang is that creating a D3D11 device takes several seconds so
> function calls which used to take a few milliseconds now take 5+
> seconds.  I did not see a mechanism to control this display mode
> programatically so I am adding code which can detect the condition
> and the logic to prevent D3D usage when 3D mode is enabled.
> 
> Of note is the change in BasicDesktopEnvironment where I requery the
> D3D apis.  DesktopEnvironmentOptions are queried in Session 0 and
> then passed on to the Desktop process.  There is a non-obvious
> problem with this as many D3D methods cannot be queried or will
> not return reliable results.  This results in a base set of options
> being set in Session 0 (which includes user / experiment overrides)
> and then passed into a session where D3D will return new values.  In
> this CL, I requery the D3D APIs and update the capturer options if
> they should be disabled.
