Feature: #20875 - Make hardcoded indexed_search parameters configurable via TS

See Issue #20875

Description

The following TS properties can now be configured for indexed search

[plugin.tx_indexedsearch.results. || plugin.tx_indexedsearch.settings.results.]
titleCropAfter = 50
titleCropSignifier = ...
summaryCropAfter = 180
summaryCropSignifier =
hrefInSummaryCropAfter = 60
hrefInSummaryCropSignifier = ...
markupSW_summaryMax = 300
markupSW_postPreLgd = 60
markupSW_postPreLgd_offset = 5
markupSW_divider = ...

Every TS property has the stdWrap property, too.

Impact

Default settings do not change old behaviour.
