Revert "video_layer_allocation: clean up unused code"

This reverts commit 05b58ad77e79efc5b4750f40b5092f945f0fff4d.

Reason for revert: UB because the shift exponent (-2) is negative
(UB happens at this line https://source.chromium.org/chromium/chromium/src/+/main:third_party/webrtc/modules/rtp_rtcp/source/rtp_video_layers_allocation_extension.cc;l=279;drc=05b58ad77e79efc5b4750f40b5092f945f0fff4d).
