SQL Server Dialect should use varchar(max) instead of varchar

[Aniket-Singla]

Description

While using Blaze Persistence, it was found that CAST_STRING function is casting the columns to varchar instead of varchar(max). The problem is varchar datatype in Sql Server is just 30 characters by default and hence rest of the value from column will be trimmed after the first 30 characters.

Expected behavior

CAST_STRING , or any other String reference should use larger values and probably varchar(max).

Actual behavior

CAST_STRING , or any other String dependent function is using varchar(30).

Steps to reproduce

Just use any function like CAST_STRING to validate the current behavour.
