feat: Combine multiple grants into one while checking state

[fionera]

Currently every grant line stands for itself, this isnt corrent since MySQL can split these up into multiple GRANT statements. This change combines them before checking for diff

Hey @fionera

I would like to thank you for taking the time submitting this PR. Would you mind adding in a test for this functionality, so we can easily confirm in the future when merging other code and regressions can be highlighted quickly.

Many thanks
Puppet IAC Team.
