Pawel Kozlowski e3422e0aed perf(ivy): minimise writes to the lView[BINDING_INDEX] / binding root (#32263)
This commit removes all the (duplicated) logic of setting lView[BINDING_INDEX]
from `enterView`. `enterView` is on the critcal path perf-wise so we should
avoid having any logic in there and minimise memory read / write.

This simple refactoring in this PR reduces time spent in noop change detection
by ~12% (from ~800ms down to ~700ms on a local machine where measurements were
taken).
