[Tree widget]: Rename filter to search

[saskliutas]

Follow up to #1538

Renamed filter to searchText on tree APIs
Made additional internal renames to match closer to the terminology in presentation-hierarchies and presentation-hierarchies-react:

• onFilterPathsChanged -> onSearchPathsChanged
• useFilteredPaths -> useSearchPaths
• FilteredTree -> SearchResultsTree
• BaseFilteredTreeNode -> BaseSearchResultsTreeNode
• FilteredTreeRootNode -> SearchResultsTreeRootNode
• FilteredTreeNodeChildren -> SearchResultsTreeNodeChildren
• FilteredNodesHandler -> SearchResultsNodesHandler
• createFilteredTree -> createSearchResultsTree
• HierarchyVisibilityHandlerImpl.changeFilteredNodeVisibility -> HierarchyVisibilityHandlerImpl.changeSearchResultsNodeVisibility
• HierarchyVisibilityHandlerImplgetFilteredNodeVisibility -> HierarchyVisibilityHandlerImpl.getSearchResultsNodeVisibility
• joinHierarchyFilterPaths -> joinHierarchySearchPaths
