Changes compared to upstream's v25.3.6.56-lts

Bug Fixes (user-visible misbehavior in an official stable release)

• Skip indexes with lambda expressions could not be applied. Fix the case when high-level functions in the index definition exactly match the one in the query (ClickHouse#80025 by @KochetovNicolai via #918)
