Merge pull request #26399 from dkurt:dk/file_storage_new_data

int64 data type in FileStorage #26399

### Pull Request Readiness Checklist

resolves #23333

Proposed approach is not perfect in terms of complexity and potential bugs. Instead of changing `INT` raw size from `4` to `8`, we check int64 value can be fitted to int32 or not.

Collections such as cv::Mat rely on data type symbol.

This PR is addressed to 5.x branch first to cover `CV_64S` Mat. Later, it can be backported to 4.x
