Make LayoutManager#getItemCount javadoc more readable.

When docs are generated for LayoutManager#getItemCount method the
{@link State#getItemCount()} is displayed as simply getItemCount()
which is confusing as it has the same name as LayoutManager#getItemCount().
This CL makes it explicit to show State#getItemCount() as State#getItemCount().

Bug: 31950286
Test: ./gradlew generateDocs looks better now.
