feat: introduce util.SplitStatements

[atzoum]

Description

util.SplitStatements splits a string containing multiple sql statements separated by semicolons:

• It strips out comments from the statements, both simple (--) and bracketed (/* */) ones.
• It can handle sql strings properly, which may contain semi colons, escaped quotes and comment character sequences without affecting the splitting behaviour.

Security

• The code changed/added as part of this pull request won't create any security issues with how the software is being used.

@kuldeep0020 this function should be more than enough to replace that
