[FE] Skip delegation descriptors during default params matching

^KT-61163 Fixed
Review: https://jetbrains.team/p/kt/reviews/11599/timeline

They can be safely skiped because we check overridden descriptors
anyway.

IMO, it's a bug that delegated descriptors are copied with default
params. But it's much harder problem, and my IMO can easily be wrong for
some weird reason.
