When capturing only one display, it is unnecessary to use
DoDuplicateAll, which allocates bitmap image memory for a rectangle
encompassing all screens and captures all displays. In this case, I
switch to DoDuplicateOne.
I have added an int parameter to GetNumFrameCaptured and
EnsureFrameCaptured to distinguish which display's skip behavior is
currently being executed.
After the modification, when capturing a single monitor in a
multi-monitor environment, only the bitmap image memory of the size of
the captured monitor will be allocated, rather than for all monitors.

I am updating Chrome Remote Desktop to apply a scale factor when using
curtain mode (i.e. a loopback RDP session) and I've found that while
the changes are applied and the desktop is scaled, DXGI stops
producing frames.
This is essentially the same issue as crbug.com/1307357 except this
issue is occurring when the DPI is changed rather than the desktop
size.
The fix is to look at the effective DPI for the source being
captured (or the primary monitor when capturing the full desktop)
and then signaling an environment change when the DPI differs.

This CL addresses an issue where the desktop appears to freeze after
resizing the desktop in a curtained CRD session when using the DXGI
capturer. This problem does not reproduce when using the GDI capturer
nor does it reproduce when the Windows session is attached to the local
console.
After digging in, it appears that the DXGI DuplicateOutput API stops
providing updated frame data. No errors are returned but yet no data is
produced. The problem is that when in this condition, there isn't a
good way to discern between this problem and a case where the desktop
is actually static.
The DxgiDuplicatorController already contains logic to attempt to
capture a frame prior to returning success after reinitialization. This
logic works fine in the console case and occasionally works in the
detached session case. What I noticed in my reproductions was that DXGI
would produce a few frames before hanging (usually 1-2 but sometimes 3
or 4). My solution is to check the session state and adjust the number
of frames we attempt to capture (I also simplified the wait logic as
there was a bug in the time calc and it seemed more complicated than it
needed to be).
One option considered would be to introduced a new differ class higher
up in the stack which would run the GDI and DXGI capturers in parallel
(instead of in the fallback configuration as they are today) however
that seemed like overkill for this specific issue.

Running clang-format with chromium's style guide.
The goal is n-fold:
* providing consistency and readability (that's what code guidelines are for)
* preventing noise with presubmit checks and git cl format
* building on the previous point: making it easier to automatically fix format issues
* you name it
