Tests: Added a lot of ydb e2e tests + some engine and types fixes

* Fixed range result.Rows(ctx) issue (go<1.23)
* Rewrited strings to BYTES ([]byte)
* Fixed count(*) issue
* Fixed datatype test
* fixed uuid issue
* rewrited ydb-go-sdk codegen to ranges back (+ upped testada go.mod version to 1.23)
* rewrited parseStringLiteral func to be more understandable
* resolved limit issue
* Rewrited slices logic not replace them
