Cleanup C# projects, code quality & style

New rules:
- Do not silence CA1805 any more
- Limit where we silence CA1707, CA1711, CA1720
- Enforce severity=warning for IDE0040
- Enforce Allman style braces
- Enforce naming conventions (IDE1006 is still severity=suggestion)

Fixes:
- Fix REFL045, CS1572, CS1573
- Suppress CS0618 when generating `InvokeGodotClassMethod`
- Fix indent when generating GD_constants.cs
- Temporarily silence CS1734 in generated code
- Fix a lot of naming rule violations

Misc.:
- Remove ReSharper comments for RedundantNameQualifier
- Remove suppression attributes for RedundantNameQualifier
- Remove severity=warnings for CA1716, CA1304 (already included in the level of analysis we run)
