vp9: Fix to SVC and denoising for fixed pattern case.
For fixed pattern SVC: keep track of denoised last_frame buffer for base temporal layer, and if alt_ref is updated on middle/upper temporal layers, force an update to denoised last_frame buffer. This allows for improved denoising on top temporal layers. Change-Id: Icbd08566027d4d2eabc024d3b7a0d959d2f8c18b
