surfaceflinger: hwc1: Add missing mActiveFrameSequence counter

In commit 66a7233a,
the mActiveFrameSequence counter was not ported to
HWC1, causing the blur layer to not capture any
screenshot after the initial one.

The end result is a static blur image that never changes.

Add the missing counter so that blur screenshots
get re-captured when needed.

surfaceflinger: Orient blur layer based on panel mount flip

As of CAF commit 1818975c,
surfaceflinger has support for rotated panel mounts.

Use the appropriate method to orient the blur layer based on it.

Commit 066aa860 reverted a piece
of code similar to this, since it was using the outdated methods
which broke compilation. Bring the code back, this time using
the appropriate method.

This partially reverts commit 066aa860.
