Update dynamic height adjusting

The current dynamic height adjusting workaround might cause that a
flicker problem happens in the collapsing toolbar and it might cause
that the collapsing toolbar has different background colors in some
setting pages. The new Material library has already supported the
dynamic height adjusting for multi-line titles, so we will use the new
mechanism instead.

Fix: 190997145
Test: go through Settings pages and check if there's a flicker problem
