#14063 Well Event: Group records of same keyword across wells

The schedule generator previously concatenated full keyword blocks
(`KEYWORD ... /\n/\n`) — one per well — producing verbose output where
each WELSPECS / COMPDAT / WCONHIST / WELSEGS / COMPSEGS / etc. block
appeared once per contributing well. Eclipse keywords are designed to
hold multiple records under a single header; the per-well repetition is
syntactically valid but bloats the file and obscures intent.

Switch `RicScheduleDataGenerator` to accumulate
`std::map<QString, Opm::DeckKeyword>` instead of raw concatenated text.
Each per-well helper now returns an `Opm::DeckKeyword`, and a new
`mergeKeyword` primitive appends its records into the accumulator entry,
creating the entry from the helper's keyword on first encounter. At
emission time each accumulated keyword is serialised once.

To support this, `RifEventKeywordFormatter` is split: each `format*`
QString function now wraps a corresponding `build*` function that
returns `std::optional<Opm::DeckKeyword>`. `RimWellEventKeyword` and
`RimKeywordEvent` expose a parallel `generateDeckKeyword` accessor.
The text-scraping `extractKeywordName` helper becomes dead code and is
removed.
