Split UtSummarySettings on two parts: UTSettings related and DBSCAN related

[amandelpie]

Description

At this moment we have strange object UtSummarySettings that collects some constants, settings (good candidates for UtSettings and UI) and some internal settings which are related to the DBSCAN clustering algorithms

I suggest moving some settings to the UTSettings and later add them to the IDEA settings to customize the summaries generation better.

Other settings should be encapsulated on the module level, without any ability to override them via file with settings or via IDEA UTBot Settings panel.
