The serialized TEvReadSet takes up a lot of memory

[Alek5andr-Kotov]

Changelog entry

Issue #18290

The TEvReadSet message can be sent again. When it was first sent, it was serialized and stored as a string. It turned out that the serialized message takes up a lot of memory space. For transactions with a large number of participants, this takes up a lot of space.

I changed it so that a copy of the data is stored to create a TEvReadSet when resending.
