Add support for MySQL 8+ for .NET Framework 4.6+ and remove local MySql.Data dependency

[DezLife]

• Added support for MySQL.Data 8.0.32 for .NET Framework 4.6 and above.
• Removed local MySql.Data reference in favor of NuGet package.
• Maintained compatibility with older .NET Framework versions using MySQL.Data 6.9.12.

Newer versions are now available, why 8.0.32 specifically?

Because this version is stable and more tested. Thus, we can definitely understand that we will not have problems with this.

In any case, if you have time to test newer versions, you can do so.

Ok, but I'd prefer 8.4.
@MrBlue, will this be accepted in the current update?
