hwc: Enable rotator during resolution change.

MDP VG pipe framesize register is not double bufferred.
It introduces corrupted frame during resolution change especially when
rotator is not used. Enable rotator to handle the transition case.

display: Use L3 DRM for non TZ content

When the GRALLOC_USAGE_PROTECTED flag is set, use L3 DRM if the
buffer isn't also allocated with the MM heap.
Per the gralloc spec, this means that such buffers shouldn't be
routed to external displays since the hardware protected path is
not available due to allocation from an insecure heap.

hwc: Add support for virtual displays

Add support for virtual displays in hwc.
The availability is detected when a valid list first appears.
Need a valid framebuffer handle to configure writeback based
on aligned dimensions.
Force full GLES virtual layers to go through HWC based on
boardconfig flag.

hwc: virtual display: Use outbuf handle width to configure xres

Use outbuf handle width to configure display xres, since that would
have the necessary alignment. The outbuf is guaranteed to be valid
by the framework during hwc_prepare.
We use the framebuffer layer's display frame to obtain the actual
width.
For example, the actual width could be 720 but the aligned width
would be 736.

overlay: writeback: Do not create writeback instance on dumpsys

Do not create a writeback instance during dumpsys.
Instead use the dumpsys to return empty if no instance exists.
This fixes the issue where
a) Unnecessary instance is created.
b) Dumpsys has garbage, if a valid instance didn't exist
